Ngoc Son temple is on a small island on Hoan Kiem Lake in the center of Hanoi, Vietnam.
It hosts a mumified giant turtle which allegedly came out of this same lake several decades ago.
This is the historical central area of Hanoi, capital of Hanoi. Hanoi estimated population 3,398,889 (2007), is the capital and second-largest city of Vietnam. From 1010 until 1802, with a few brief interruptions, it was the political centre of an independent Vietnam. It was eclipsed by Huế during the Nguyen Dynasty as the capital of Vietnam, but Hanoi served as the capital of French Indochina from 1887 to 1954. From 1954 to 1976, it was the capital of North Vietnam.
