Tran Quoc - National Founder pagoda situated at Thanh Nien street and between Hanoi West and Truc Bach Lakes. It is not only oldest but also almost sacred pagoda for Hanoi people, moreover it is one of attractive destination that traveller should not get out of it.
It was built in 541 and completed in 545 under the reign of King Ly Nam De (544-548) under its original name of Khai Quoc (National Founder). It was initially built on the bank of the Red River (then West Lake and the Red River met). Tran Quoc is considered as a cultural symbol of Vietnamese Buddhism, the oldest pagoda.

Standing at one end of Thanh Nien Road, one can see the towers of the pagoda rising above the lake’s surface. In the pagoda’s garden stands a Bodhi(banian tree)- in 1959, on his visit to Vietnam, Indian Prime Minister Razendia Prasat offered the Pagoda a bodhi tree as a gift. The plant was grafted from the holy bodhi tree where Sakyamuni sat in zen (meditation) position and achieved enlightenment in India 25 centuries ago. Now the bodhi tree is easily recognizable from its heart-shaped leaves, taken from a cutting of its original tree. Today, the tree green and luxuriant, shading over part of the pagoda's yard. These days, Tran Quoc Pagoda, as a religious relic with a spectacular ­surrounding scenery, is a favourite stop-over of so many foreign visitors and pilgrims.

One Pillar Pagoda – Hanoi Iconic Pagoda

Situated inside Ho Chi Minh ‘s mausoleum complex, One Pillar pagoda become an attractive tourist destination with its architectural splendour and one of Vietnam’s two most iconic pagodas.

The One Pillar Pagoda (Vietnamese:Chùa Một Cột, formally Diên Hựu tự , which litterally means “long lasting happiness and good luck”) is a historic Buddhist temple in Hanoi, the capital of Vietnam. As you visit Hanoi, you may come to various other monuments, parks and historical places.
The Legendary story:According to legend, ageing Emperor Ly Thai To of the Ly dynasty, who had no children, used to go to pagodas to pray to Buddha for a son. One night, he dreamt that he was granted a private audience to the Bodhisattva Avalokiteshvara, who was seated on a great lotus flower in a square-shaped lotus pond on the western side of Thang Long Citadel, gave the King a baby boy. Months later, when the Queen gave birth to a male child, the Emperor ordered the construction of a pagoda supported by only one pillar to resemble the lotus seat of his dream in the honour of the Bodhisattva Avalokiteshvara. According to a theory, the pagoda was built in a style of a lotus emerging out of the water.
Formation: Emperor Ly Thai Tong had this temple constructed in gratitude for the mentioned significant legendary event in 1049, by erecting a pillar in the middle of a lotus pond, and a temple of lotus-shape, exactly similar to what he saw in the dream. This unique shape of the pagoda together with the special story has been of great absorption to hundreds of thousands of international tourists!
This Pagoda was located in what was then the Tây Cấm Garden in Thạch Bảo, Vĩnh Thuận district in the capital Thăng Long (now known as Hanoi. It was built of wood on a single stone pillar 1.25 m in diameter, and it is designed to resemble a lotus blossom, which is a Buddhist symbol of purity, since a lotus blossoms in a muddy pond. Before the pagoda was opened, prayers were held for the longevity of the monarch, hence being considered a temple at that time. During the Ly Dynasty era, the temple was the site of an annual royal ceremony on the occasion of Vesak, the birthday of Gautama Buddha. A Buddha-bathing ceremony was held annually by the monarch, and it attracted monks and laymen alike to the ceremony. The monarch would then free a bird, which was followed by the people.
As time went by, the pagoda succumbed to many ravages caused by the colonial powers. In 1954, the French Union forces destroyed the pagoda before withdrawing from Vietnam after the First Indochina War, and it was rebuilt afterwards.
Today’s form: What you see today of the pagoda is a new form recovered in 1955 when it was refurbished with a concrete pillar from its remnants by the Vietnamese government. Today's structure can be just called the replica of the original pagoda, which was a large building. Locals believe that if you pray here, it will invoke well-beings and prosperity.
Opening time: The pagoda is open daily from 08:00 a.m to 05:00 p.m. Entrance is free.
Note: Remember to wear full-length clothes as you visit the One-Pillar Pagoda as well as other pagodas in the nation.
