Ngoc Son Temple, or Temple of the Jade Mountain, is located on a small islet at Hoan Kiem Lake in Hanoi. The temple was founded in the 14th century but most of its current structures were built in the 18th century.
Surrounded by water and shaded by trees, this small temple is dedicated to General Tran Hung Dao, who defeated the Mongols in the 13th century, La To, the patron saint of physicians, and the scholar Van Xuong.
Inside you’ll find some fine ceramics, a gong or two, some ancient bells and a glass case containing a stuffed lake turtle, which is said to have weighed a hefty 250kg. The present building reflects the Chinese style favored by the Nguyen rulers of that time.
