Hoan Kiem Lake (Vietnamese spelling: hồ Hoàn Kiếm), or Sword Lake (hồ Gươm), is the symbol of Hanoi. Located in the center of the city, it represents over a thousand years of history and culture.
Literally translated as ‘Lake of the Restored or Returned Sword’, it’s a freshwater lake covering some 12 hectares. The central district of Hanoi also takes on the same name.
The Legend of Hoan Kiem Lake

The name Hoan Kiem Lake (還劍湖) originated from a legend of King Lê Thái Tổ or Lê Lợi in the 15th century. The story goes that the king coincidentally received a divine sword and used it to defeat the opposing Chinese Ming Dynasty.
After the war, while relaxing on his boat, a mystical golden turtle emerged from the water and asked for the sword back. The turtle claimed to be sent by the Dragon King of the Sea (Long Vương) to retrieve the sword that King Lê came across.
The History of Hoan Kiem Lake

According to a map of 6 centuries ago, Hoan Kiem Lake used to be a direct branch of the Red River (sông Hồng). Nowadays, the lake is supplied through an underground water system connected to the river.
In the 16th century, a Trinh Lord (chúa Trịnh) built the Ta Vong House (đình Tả Vọng) on Ngoc Son Island (đảo Ngọc Sơn). It was rebuilt into the Thuy Ta House (Thuỷ Tạ) of today which is a small wooden sala pavilion and a nice resting spot.
He also separated the lake into the left Ta Vong (hồ Tả Vọng) and the right Huu Vong (hồ Hữu Vọng). The Trinh Lords were the de facto rulers of northern Vietnam (Đàng Ngoài) while the Nguyen Lords ruled the south during the Later Le Dynasty.
During the time of King Tu Duc, the Huu Vong Lake was called the Marine Lake where military training was held, while the Ta Vong Lake kept the name Hoan Kiem. In 1884, the French covered up the Marine Lake for the expansion of Hanoi.
Things to See and Do around Hoan Kiem Lake
Hoan Kiem Lake is really nice for an early morning stroll if you’re up for it. Alternatively, the late afternoon is also a good choice. The temple on the lake, or ones in the side streets nearby, are key attractions. Temples generally open from 7 AM to 6 PM and it’s best to wear clothing covering knees and shoulders when you pop in.

Ngoc Son Temple and The Huc Bridge

Ngoc Son Temple (đền Ngọc Sơn) is on Ngoc Island (đảo Ngọc) and the spiritual heart of Hoan Kiem Lake. The name translates to “Temple of the Jade Mountain”- 玉山.
Visitors can walk across the bright red The Huc Bridge (cầu Thê Húc) which was added in 1865 for an easier crossing. The temple worships Wenchang Wang (Văn Xương Đế Quân)— the God of Culture and Literature in Taoism along with the Vietnamese King Trần Hưng Đạo.
The original temple existed from the time of King Lý Thái Tổ in 1010, but was destroyed during the Tran Dynasty, then rebuilt in the 19th century into what we see today. The design is Northern Vietnamese along with ancient writings on the walls and poles.
Pen Tower and Inkstone

The Pen Tower (Tháp Bút) is actually a calligraphy brush tower. There’s an inkstone (Đài Nghiên) on top of the third gate on the way to Ngoc Son Temple. These two literary symbols were also added in 1865.
Hanoi Turtle Tower

The Turtle Tower (tháp Rùa) is the iconic symbol right in the middle of Hoan Kiem Lake. It was built from 1884 to 1886 with Gothique walls and a traditional Vietnamese roof. During the French colonial period, there was a Statue of Liberty placed on top of the tower but it was destroyed in the 1950s.

There actually used to be four turtles in the lake. There were disagreements about exactly what species they were. One of the most accepted conclusions was they were a new species called Rafetus leloii or Rafetus Vietnamensis.
All four of the turtles have since passed away. One is preserved in the Ngoc Son Temple, one in the Hanoi Museum, one was accidentally killed and eaten when sojourning ashore in 1962, and the last finally passed away in 2016.
Water Puppet Show at Thang Long Theatre

Thang Long Water Puppet Theatre (Nhà hát Múa rối Thăng Long) is the most highlighted water puppet show (múa rối nước) in Hanoi. The stories revolve around historical, cultural, and traditional aspects of Vietnam.
There are five shows every day afternoon. Language is not a problem since there’s hardly any dialogue and the performances are designed to be understood from sound and visuals.
