Hoan Kiem Lake, or “Lake of the Returned Sword,” is the geographical and spiritual center of Hanoi. It is a vital green space and a social hub, acting as a historical bridge between the bustling Old Quarter and the modern city center.
I. Legend, History, and Culture
The Legend: The lake is famously associated with the Legend of the Returned Sword. According to folklore, in the century, Emperor Lê Lợi was given a magical sword by the Golden Turtle God (Kim Quy) to defeat the Chinese Ming invaders. After his victory, a giant turtle emerged from the lake while the Emperor was boating and reclaimed the sword, returning it to its divine owners. The lake was thus renamed Hoàn Kiếm (Returned Sword).
Turtle Tower (Tháp Rùa): This small, iconic three-story tower stands on a tiny islet near the southern end of the lake. Built in the century, it commemorates the Golden Turtle legend and is an enduring symbol of Hanoi. You can admire its silhouette from the shore, but the tower itself is not open to visitors.
The Heart of Hanoi: The lake has been a central gathering spot for centuries. Today, it reflects Hanoi’s daily rhythm, from early morning Tai Chi and jogging sessions to the vibrant weekend pedestrian street activities.
II. Key Attractions and Activities
Ngoc Son Temple (Đền Ngọc Sơn): Located on Jade Island in the northern part of the lake, this temple is dedicated to General Trần Hưng Đạo (who defeated the Mongols in the century) and other historical scholars.
The Huc Bridge (Cầu Thê Húc): Meaning “Bridge of the Rising Sun,” this striking, bright red wooden bridge connects the lake’s shore to Ngoc Son Temple and is one of Hanoi’s most photographed landmarks.
Hoan Kiem Lake Walking Street: Every weekend, the streets immediately surrounding the lake and parts of the Old Quarter are closed to motor traffic, transforming the area into a lively pedestrian-only zone.
Time: Typically from Friday to Sunday.
Activities: The walking street features street performances, live music, traditional Vietnamese folk games, and a bustling atmosphere.
Water Puppet Theatre: The famous Thăng Long Water Puppet Theatre is located right by the lake, offering a unique Vietnamese art form experience.
