Đền Ngọc Sơn, or the Temple of the Jade Mountain, sits on a small island in Hanoi's iconic Hoàn Kiếm Lake, connected by the striking red Huc Bridge. This active religious site is dedicated to Confucian scholar Van Xuong and national hero Tran Hung Dao, as well as the legendary turtle that returned a magical sword to the lake. Visitors cross the wooden bridge, painted a vibrant red, and enter a serene courtyard with incense smoke and ancient trees. Inside, you'll find altars, calligraphy, and a preserved giant turtle shell, a tangible link to the lake's myth. The temple offers a peaceful retreat from the bustling Old Quarter and provides insight into Vietnamese spiritual life. Its location at the lake's northern edge makes it a natural stop on any Hanoi walking tour.
