Hoàn Kiếm Lake, Hanoi (must see)

Hoàn Kiếm Lake holds a storied place at the heart of Hanoi. Also known as Sword Lake, this 12-hectare freshwater lake is a central feature of the city's public and historical life. Located in Hanoi's historical center, the lake is not only a major scenic spot but also a focal point for the city's public life, surrounded by vibrant streets and bustling local markets.

Originally named Green Water Lake (Hồ Lục Thủy) for its distinctive watercolor, the lake's present name, which means "Lake of the Returned Sword," is derived from a legendary event. The tale recounts that Emperor Lê Lợi, after defeating Ming China, was approached by a Golden Turtle God (Kim Qui) while boating on the lake. The turtle god requested the return of a magical sword, Heaven's Will, given to Lợi by the Dragon King (Long Vương) to aid in his battle against the Chinese. Acknowledging that his mission was accomplished, Lợi returned the sword to the turtle. This pivotal event led to the renaming of the lake to commemorate the sword's return.

The Turtle Tower (Tháp Rùa), situated on a small island near the center of the lake, is a prominent landmark associated with this legend. It stands as a silent reminder of the lake's mythological past. The lake was once home to the large soft-shell turtle species Rafetus leloi, named in honor of the emperor. Although the last known specimen was found deceased in 2016, the species remains emblematic of the lake's rich biodiversity.

To the north, the Jade Islet is connected to the lake's shore by the striking vermilion-red Thê Húc Bridge, which means "Perch of the Morning Sunlight". Atop the islet sits the Temple of the Jade Mountain (Ngoc Son), erected in the 18th century. This temple honors notable historical figures such as Tran Hung Dao, a military leader known for his victories over Mongol invaders; Van Xuong, a revered scholar; and Nguyen Van Sieu, a renowned writer who refurbished the temple in 1864, lending it its current appearance.

Today, Hoàn Kiếm Lake remains a vital part of Hanoi’s cultural fabric, attracting visitors with its serene beauty and rich history, encapsulating a blend of natural charm and cultural significance.
