Phat Diem Cathedral, Architectural Masterpiece Outside Hanoi, Vietnam

If you are traveling to Hanoi, Vietnam and you love to see some amazing architecture, you should not miss the Phat Diem Cathedral that is located about two hours outside Hanoi, Vietnam. This Cathedral is also featured in Graham Green’s book, The Quiet American.

The Phat Diem Cathedral is located about 123 kilometers (76 miles) outside Hanoi, Vietnam. The Cathedral is a very unique architectural structure that was designed and built in the mid-1800s by Father Six, a Vietnamese Catholic Priest. The Cathedral complex has a bell tower, a Cathedral and also smaller chapels and grottoes. Graham Greene the famous British author featured the Phat Diem Cathedral in his book The Quiet American. American bomber dropped eight bombs on the Cathedral in 1972.

The Architect – Father Tran Luc or Father Six

The architect of Phat Diem Cathedral complex was Father Tran Luc or as he was known Father Six. In French, he was called Pere Six and in Vietnamese, he is known as cu Sau.

Father Six’s real name was Triem. He was born in 1825 in My Quan village in Nga Son district in Thanh Hoa province in North Vietnam. In 1858 he became a deacon, but before he could become a priest he was arrested and sent to Lang Son. During this period many Catholic priests were arrested and put in prison as the Emperor of Vietnam did not like or trust the Catholics. It was when he was in prison that he became known as Father Six.

In the 1860s, Father Six was still in prison, but he was allowed to go to his hometown for a short period. It was during that time that he took the opportunity to be able to be finally ordained a priest. He was released from prison in 1863 and was eventually put in charge of the Phat Diem parish.

Father Six was a pastor for the Phat Diem parish for 34 years. When he first came to Phat Diem the area had about 2,000 catholic parishioners, but when he died there were over 10,000 Catholics in the area. At his funeral in 1899, it is said that over 40,000 people came to honor him and his life. There is little doubt that he was greatly loved and respected.

It took Father Six about 34 years to build the cathedrals. It took him 10 years to prepare all the materials and 24 years for the actual building. Money for the building of the cathedral was not given by the French or any foreigners, but Father Six raised the funds from many poor Vietnamese in the local area.

There is little doubt that if this Cathedral had been built by a foreigner it would have looked more like the European style churches of its time. Instead, it has become one of the most important and unique architectural churches in Asia, as it built in the Far-Eastern architectural style as it showed that East and Western design styles could be mixed.

It can be said that Father Six, was as all great architects or designers, a man who had the vision to think outside-the-box and the norms of his day. He clearly understood his parishioners, the world around him and built a church that spoke and resinated to that world.

Father Six was not just skilled in architecture, but he also excelled in politics, Chinese literature and Vietnamese poetry. He composed prayers, catechisms, and educational lessons.

He was ahead of his time for a new type of evangelism called “inculturation. Inculturation is defined as:

“Inculturation is the term that Catholic leaders and theologians have used in recent decades to denote a process of engagement between the Christian Gospel and a particular culture. “

Dennis M. Doyle

Father Six was a forerunner in inculturation. Similar to the Jesuit Priest Matteo Ricci and his work in China and the Jesuit missionary Roberto de DeNobili and the work he did in India

Laying the foundation of the Phat Diem Cathedrals

The land and area that Father Six and his church was located on was basically a swamp or marshland. To stabilize this ground for the building of the chapels he had to first prepare the land for building. But they also had to use materials that were readily available to them.

There was no machinery during this time, so everything had to be done by hand. Millions of bamboo stakes were driven about 30 meters into the ground until they could not drive them down any further. Then earth and gravel were poured on top of that and trampled on by men and water buffaloes. Then bamboo rafts were made and put on top of that. One reason why bamboo was used is because of not only its strength but also because it does well in water. They did all this before any actual foundations were ever laid.

These foundations have withstood the test of time. Not only are they very stable today but even with 8 bombs dropped on the Cathedral by the American forces in 1972 (see our section below) the cathedral compound has continued to stand strong.

Procuring materials for the Phat Diem Cathedral

One of the most difficult questions Father Six had to resolve was what materials could he use for the building of the cathedrals. He needed to use materials that were easy to find, cost-effective and would also be long-lasting.

Almost all the materials had to be brought in from other places as materials are not readily available in this area. Even today this area is known for basket weaving and farming.

Here are some of the materials and where they had to come from:

  • Stone – The stone came from the Thien Duong area which is about 30 kilometers or 19 miles away.
  • Marble – The marble came from Thanh Hoa Province which is about 60 kilometers or 37 miles away.
  • Timber – The timber had to come from several places. Some came from as far as Nghe An Province which is 200 kilometers or 124 miles away and Thanh Hoa Province which is 60 kilometers or 37 miles away and also Son Tay Province which is 150 kilometers or 93 miles away.

By today’s standards these places may not seem that far, but remember this was in the mid to late 1800s when transportation and transporting these materials would have been extremely difficult. There is no wonder it took him over 10 years just to gather and find the materials. It would have taken them quite a while to even find, locate and transport these materials to the construction site.

Some of the huge blocks of rock would weigh up to 20 tons. Other large trunks of the trees weighed as much as 7 tons. They brought a lot of these heavy materials down by bamboo rafts through the waterways and canals and then would unload them at high tide. They would pull them off the rafts and to the building site by men and water buffaloes.

Constructing the Phat Diem Cathedral

Getting the materials was very challenging as was also the construction. The area this cathedral is located is still quite a small town today when compared to other areas in Vietnam as Hanoi, Ho Chi Minh City or even Danang.

During this time all of the construction had to be done completely by hand as there was no machinery that could be used. Even by today’s standard of construction, these cathedrals would have been difficult but during that time period, it was a very ambitious undertaking.

Here is some information on the construction of the Phat Diem Cathedral:

  • Stonework – The stones would have had to have been dragged in place. As there was no cement during this time so the stones were mortared in place using sand and lime. They would have had to have allowed time for each block to set firmly in place.
  • Woodworking – The stone porch entrance of the cathedral was built firm to help to allow for the hoisting of the wood beams. Each of the different partitions in the Cathedral was assigned to a group of carpenters. After just three months of work, some of the foundation wood beams could be put in place so that other beams could then follow. Some of these wood beams weighed at least 25 tons each.

When you think about the procuring of materials and the construction it is really a testament to Father Six and his ability as an architect, engineer and project manager in the building of this cathedral It is also a testament to the men who worked on the construction site hauling and lifting those heavy stone, marble, wood, and other materials without any machinery and only with the use of very difficult manual labor and some water buffalo to help them.

Phat Diem Cathedral’s entrance

When I first entered the Phat Diem Cathedral’s entrance area, the first thing you will notice is a pond with a small island that has a statue of Christ outstretching his hands. It reminded me of the Christus Statue at the Evangelical Lutheran Church in Denmark, except for in this statue Christ’s hands are outstretched higher than the original Christus statue. The Phat Diem Christ statue is called “Christ the King.”

The other thing that struck me was the pond itself. Most Buddhist Temples in Vietnam have a pond in front of them, so besides the Christ statue and the cross that you could see on the horizon, the setting of the Cathedral from the beginning looks a lot like a Vietnamese Buddhist Temple.

Visitors will also notice is that to enter any building in the Phat Diem Catherdal complex, you must step over the threshold to enter. This is the same way that you must step over the threshold to enter a Buddhist temple. The reason for this is that this is considered a mark of respect.

Phat Diem Cathedral’s bell tower

The bell tower is the structure near the lake and also the first building you see when you enter the cathedral complex. The bell tower was built to represent a typical Vietnamese communal house that is in most Vietnamese villages. Also located in the back of the bell tower in the courtyard between the bell tower and one of the cathedrals is Father Six’s tomb.

The building is almost square and was built without any doors. Above the central entrance, you can see four large Chinese style characters that translate to mean “precious seat of the Holy body.” The smaller characters tell the date of the building, which translates as “Holy Thursday 1899.” On the other side is a Latin inscription that reads “Capella in Coena Domini” which translated means “Chapel for the last supper.”

The bell tower has a very spacious interior. In the center of each section is a large stone slab. This is a communal kind of seat where Vietnamese would sit upright, crossed legged. The large slab in the middle section was said to have belonged to the royal hall of the Tay Giai Citadel in Thanh Hoa Province.

You can look at the bell tower and you can almost imagine the thousands of Vietnamese who have sat on these stone slabs talking about everything from Christian teachings to about love or just daily life. How many friends were made on those slabs or how many proposals or love matches were made because of those conversations.

On the walls around the bell tower are some carved stone reliefs of some saints, along with the bamboo carved stone bars. On the first floor hangs a large drum. This drum is used only on Sundays and festival days as a way to accompany the ringing of the larger bell.

On the very top floor of the bell tower hangs a larger two-ton bell. The bell is struck by the means of a wooden ram and it is said when the bell rings it can be heard for at least 10 kilometers away. On a clear day from the top of the bell tower, you can see the seaside to the south and the mountains to the west.

The bell tower was the last structure in the complex to be completed. There are also many who feel like this is also the finest building in the entire complex.

Right behind the bell tower is the Phat Diem Cathedral. The cathedral has five smaller chapels and some grottoes surrounding it.

On the front of the stone facade of the Cathedral is a hymn in Latin to honor, Mary the mother of Jesus and also a dedication of the Cathedral to Our Lady of Holy Rosary. This was also signed by Father Six in 1891.

On the very top of the central tower of the Cathedral are two angels who are holding up a cross and some other angels are blowing trumpets along with four Chinese style characters that say “foreboding of judgment day.”

Here are some facts about the outside and structure of the Cathedral.

  • The towers are made of bricks
  • The five porches are made of stone
  • The central porch is a piece of stone carved with rose bushes that are spreading its twigs among 17 angels.
  • Above the stone, porches are 15 stone reliefs representing different parts of Mary and Joseph’s life, also known as the 15 mysteries of the rosary.
  • There are 5 entrances that are 9 meters deep (29 feet) built of stone that also leads to some carved doors.
  • The roof rests on 52 wooden pillars, 16 of which are 11 meters high and 2.60 in circumference. These pillars weigh about 7 tons each.
  • On the side of the outside wall, you can see two windows made of stone and a carved lion.

When you entered the Cathedral, everyone should be impressed with not only the magnitude of the interior but how quiet and reverent it feels.

Here is some information about the inside of the Cathedral:

  • Above each angel that is holding a holy basin are sentences in Latin encouraging Christians with the right attitude, they need to have when they come to pray.
  • There are some magnificent hand-carved gold lacquer pillars. If you are interested in Vietnamese lacquer you are read this blog on How to Manufacture Vietnamese Lacquer? by clicking here.
  • There is a very prominent statue known as “Our Lady with Infant Jesus”.
  • Surrounding the statue are pictures of various Saints.
  • On the glass windows are pictures of six martyrs, of these six martyrs five are Vietnamese and one is European.
  • The top picture is of “Our Lady giving the Rosary to St Dominic.
  • The old altar in the rear was cut by a single slab of white stone. This altar is beautifully chiseled.
  • The front altar is new and also made of a single slab of stone. This altar was consecrated on 6th October 1991 during the 100 years anniversary of the Cathedral.

The Phat Diem Chapels

Father Six built 4 smaller chapels surrounding the Cathedral. A fifth chapel was the Stone chapel that was built just a bit further away. Some people refer to these smaller chapels to the “Ladies in waiting.” Each one of these chapel structures is similar but also at the same time unique.

Here is some information about these five chapels.

  • Saint Joseph Chapel – The front chapel is on the west side and was built entirely by wood. On both walls of the choir are some stone reliefs depicting various episodes of Saint Joseph’s life. A choir inside a church is defined as between the high altar and the nave, used by the choir and clergy.
  • Saint Peters Chapel – Directly behind the Saint Joseph’s is located Saint Peters Chapel which was built entirely out of jack wood. Jackwood is wood from the Jackfruit tree Father Six dedicated this chapel to the patron Saint Peter. On the choir before the windows decorated with stone bars are reliefs portraying the twelve Apostles whose names are written in the ancient Vietnamese script. The altar is a single block of stone weighing twenty tons.
  • The Immaculate Heart or The Stone Chapel – Perhaps the most famous of all the smaller chapels in the stone chapel. This chapel was built in 1883 and was the first chapel to be built. Everything in this chapel was made of stone including all the floors, pillars, beams, walls towers, and the altar. The facade of the outside is carved with stories including the story of the Sword Lake in Hanoi. You can also see a Phoenix and a lion which has smiling human faces. In the niche of the central tower is engraved a prayer to the “Immaculate Heart of Mary” in four languages. Even though this is all made from stone, the interior still looks light due to the high gloss marble decorations, beautiful windows and also the sculptures.
  • The Sacred Heart Chapel – On the east side of the Cathedral is the Sacred Heart Chapel. This chapel has a three-tower facade and beautifully carved doors. It was said that a French Official asked Father Six to bring these doors to Paris for an exhibition but Father Six refused as he said the doors had already been given to God.
  • Saint Roch Chapel – This chapel was built in 1895 and was originally dedicated to Saint John the Baptist. The chapel was renamed after Saint Roch for gratitude for the area to be delivered from the cholera epidemic in 1923. Except for the altar that is made of stone the rest of the chapel is made of Jackwood.

The Phat Diem Cathedral Grottoes

All around the Chapels and the Catherdral area is also some grottoes. Here is some information on grottoes:

  • The Calvary Grotto – The calvary grotto is in front of the Stone Chapel. The grotto has a statue of Christ on the cross at calvary and under the statues, you can see a cave that looks to represent Christ’s tomb.
  • The Bethlehem Grotto – The Bethlehem Grotto is east of the Calvary Grotto. This was originally named the Sepulchre Grotto and it was built by Father Six in 1875 to help test the stability of the soil before starting construction.
  • The Lourdes Grotto – This is east of the Bethlehem Grotto. As you visit the Lourdes Grotto you can stop to get a view of the Bishops house where the right-wing of the house was built by Father Six over 100 years ago. This grotto has some beautiful trees and under some of the trees are the gravesites of two Parish Priests of Phat Diem plus a layman who was martyred in the 19th Century.

Graham Greene’s 1951 Visit to Phat Diem Cathedral

Graham Greene, the famous British author of the book The Quiet American, was intrigued by the Phat Diem Cathedral. He came to the Phat Diem Cathedral in 1951 with his friend Trevor Wilson, who at the time was based at the British Embassy in Hanoi. Graham Greene was a practicing Roman Catholic.

In 1951, the French and Viet Minh were fighting, but the area near Phat Diem Cathedral was controlled by a third group under the guidance of a Catholic Prince Bishop, Le Huu Tu and another adjoining Diocese of Bui Chu. They had their own army of about 3,000 men and had about 500,000 Catholics under their control along with about half a million Buddhists.

Bishop Tu was extremely nationalistic. He did not want to allow the French the rights in his diocese and the Viet Minh were not friendly to the Catholic population.

Phat Diem Cathedral became involved in the war between the French and Viet Minh. In 1953 French artillery shells hit the East wing of the Cathedral collapsing part of the roof.

In speaking about Greene and Wilson’s visit to Phat Diem, Kevin Ruane said:

“The Catholic Greene was captivated by Phat Diem, as was his friend and co-religionist Wilson. Greene also admired Tu’s independence: “my number-one enemy is the French,” Tu told him,“after which come the Communists.” On this first occasion Greene spent just thirty-six hours in this “medieval Episcopal principality” before returning to Hanoi on 1 February. “

Kevin Ruane

Grahame must have been very impressed with the Phat Diem Cathedral as it is in his book The Quiet American. In fact, the Phat Diem Cathedral is one of the major places or settings for the book The Quiet American. When you visit Phat Diem and you see the architecture, you can see why it captivated Graham Greene so much that he would put it in his novel The Quiet American.

The 1972 American Bombing of Phat Diem Cathedral.

On August 15, 1972, American bombers dropped eight bombs on the Phat Diem Cathedral. They meant to hit all the buildings but by pure luck, many of them were missed. If the bombs had all hit their intended targets, the entire Catherdal complex would have probably been destroyed.

The bombs hit from the bishop’s house to the pond area. One bomb exploded on an open space on the west side of the Cathedral. It flattened the Saint Peter’s Chapel and caused Saint Joseph Chapel to tilt while sending 36 stone slabs to the ground.

This bomb also almost blew away all the tiles off the roof of the Cathedral along with most of the wooden doors. Fifty-two out of fifty-six doors were damaged as well as the stone reliefs on the station of the cross. Inside the Cathedral there was also damage to the altar, as all the gold and lacquer work was covered in dust. Due to the bomb blast, the Cathedral tilted 15 to 20 degrees and it was only due to the strong stonework of the facade, that kept the Cathedral from not completely collapsing.

During this time the war was in full swing and America was dropping a record number of bombs on North Vietnam. During December of 1972 America had the Christmas bombing campaign where 20,000 tons of bombs were dropped on North Vietnam.

The Phat Diem diocese needed to decide if they would wait until the end of the war when the bombing stopped to repair the cathedral or if they would repair it now. They were worried if they waited too long the damage to the Catherdral would be irreplaceable especially for the gold lacquer altar in the Cathedral.

The decision was made that despite the war and the possibility there could be additional bombs on the Catherdal they needed to start to repair the Catherdal complex as soon as possible. The repair work started on the Phat Diem Cathedral in October 1972.

The bomb craters were filled, wood was sawed to repair the wooden doors and tiles were brought in to repair the roof. About 200 people came to help repair the cathedral, most of them unpaid. Some of the carpenters worked for months unpaid and just received some donated rice from local people so they could eat. It took over two years to completely repair the damage done by these eight bombs to the Phat Diem cathedral complex.


The Phat Diem Cathedral is worth visiting. Not only is it a wonderful architectural treasure but it also has a fascinating history of how the Cathedral complex was constructed. When you visit there you can see why a renown author like Graham Greene would have been so intrigued with the Phat Diem Cathedral complex.
