Hoan Kiem Lake

Hoan Kiem Lake

Hoan Kiem Lake (Ho Hoan Kien), also known as the Small Lake, is located in the central area of Hanoi's Old Quarter and is considered the premier scenic spot in Hanoi. Surrounded by lush greenery and clear, mirror-like waters, it offers a picturesque setting. If you rise early—around six o'clock—you can see locals gathering by the lake before heading to work, diligently practicing tai chi or engaging in other morning activities. In the middle of the lake lies Turtle Tower (Thap Rua), a small yet elegant structure topped with a star. The lake’s center is also home to the One Pillar Pagoda and Jade Mountain Temple (Ngoc Son Temple). Inside Jade Mountain Temple, three deities are worshipped: Guan Yu, King Hung Dao, and the God of Literature. Outside the temple stands a five-story stone tower whose top resembles a brush pen, while the main gate is formed by four stone pillars shaped like pens, accompanied by a Chinese couplet that reads: “Approaching water and ascending mountains, the journey gradually reveals better scenes; seeking origins and exploring antiquity, one finds boundless beauty within.” This symbolizes success in the imperial examinations. Legends about Hoan Kiem Lake vary, but all revolve around Emperor Ly Thai To receiving a divine sword and using it to repel the Ming invasion (1418–1428)—a tale reminiscent of the Vietnamese version of the King Arthur legend and Excalibur. After finally overthrowing the Ming dynasty, Emperor Ly Thai To is said to have arrived by boat at the center of Hoan Kiem Lake to return the sacred sword to a giant turtle. According to the legend, after reclaiming the sword, the turtle immediately dived back into the lake and disappeared forever. Hence, the lake was named “Hoan Kiem,” meaning “Returned Sword.”
