Tran Quoc Pagoda, located on a small peninsula in Hanoi's West Lake and known in Vietnamese as Chùa Trấn Quốc, is said to be the oldest pagoda in the capital.

It features an eleven-storey brick pagoda, with a white marble pinnacle of seven towering and tapering lotus flowers, a number reminiscent of those at the Buddha's birth (fig.), and topped by a calabash, from which a needle-like spire emerges. It has niches at every level and on all sides, that each houses a marble Buddha image (fig.). When initially constructed, the temple was sited on the shores of the nearby Red River, outside of the present-day city dyke and was relocated in 1615 to its present location on West Lake.

Originally an island, a land bridge now connects the site to a larger causeway that in turn links the North and Southside of the lake to the mainland by road.
