Ho Hoan Kiem and the island temples of Hanoi
Published on 09/23/2026 at 19:54 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Ho Hoan Kiem is a freshwater lake in the historic centre of Hanoi. Its surface holds Turtle Tower, while Ngoc Son Temple occupies an island beside the northern shore. The lake’s name means “Lake of the Returned Sword”, linking the landscape with a fifteenth-century story about Le Loi and a sacred blade.
Ho Hoan Kiem: a lake named by legend
The lake has carried several names. Luc Thuy means “Green Water”, while Thuy Quan refers to naval activity. The name Ho Hoan Kiem entered the landscape through the legend of Le Loi, who led the Lam Son uprising against Ming rule.
In the story, Le Loi received a magical sword and used it during the conflict. After victory, a golden turtle appeared while he was on the lake. The sword returned to the water, and the lake became Ho Hoan Kiem. The legend remains attached to the lake’s name, its tower and its civic identity.
Turtle Tower in the middle of the water
Turtle Tower rises from a small mound in Ho Hoan Kiem. Its brick walls, arched openings and compact vertical form create a distinct landmark between the surrounding streets and the lake surface. The tower was built in the nineteenth century, with construction associated with the years 1884 to 1886.
The tower is not a temple interior open to ordinary movement across the water. It is a visible structure set apart from the shore. Its name recalls the turtle in the lake legend and the large turtles historically associated with Ho Hoan Kiem. The red roofs and dark vegetation around the shoreline frame the tower from several directions.
Ngoc Son Temple and The Huc Bridge
Ngoc Son Temple stands on Jade Island beside the northern part of Ho Hoan Kiem. The temple complex contains religious and historical associations with Tran Hung Dao, Van Xuong and other figures connected with Vietnamese spiritual and scholarly traditions.
Access to the island crosses The Huc Bridge, a red wooden bridge whose name refers to reflected morning light. The route links the lakeside promenade with a compact group of gates, courtyards and temple buildings. Nguyen Van Sieu presided over the bridge’s construction in 1865, giving the approach its nineteenth-century form.
