Hoan Kiem Lake, also known as Sword Lake, has accompanied with the historical development of Vietnam and associated with the spiritual Vietnamese’s life. From above looking down on the lake like a huge mirror with green water.
Hoan Kiem Lake used to called Luc Thuy Lake ( Green Water Lake) because the water is green all the year around. And it was named Hoan Kiem Lake from 15th century with the legend “The Golden Turtle claim sword”. The Legend tells that during the war against the Minh aggressors (1417-1427), King Le Thai To was given a precious fairy Sword by the Golden Turtle God. After 10 years of continuous struggling, the King finally defeated the Chinese and reclaimed the nation’s independence. After that, on a nice day, while boating on Luc Thuy Lake, a large turtle came towards him. It immediately grabbed the sword with its mouth and submerged. He realized that the God must have lent him the sword to drive back the enemy, but then that his nation was free, the sword must be returned. Hence, King Le Thai To named Hoan Kiem Lake or Lake of the Restore Sword.
In addition, the lake also associates with the famous architectural works such as: Tortoise Tower, Ngoc Son Temple, and The Huc Bridge. In the middle of the lake is Turtle Tower, so as to remind Vietnamese people of the Turtle God of his great assistance. Besides, the red Huc Bridge, which means "where the sun light is absorbed", curves like shrimp and led into Ngoc Son Temple. Hoan Kiem Lake has two small islands: Turtle Island and Ngoc Island where Ngoc Son Temple is located. In 1865, Nguyen Van Sieu remodeled Ngoc Son Temple on the Ngoc Island. On the Ngoc Boi Mountain, he built a tower of brush and on the tower, there were three words: "Ta Thien Thanh" or "write on blue sky". That tower is called But Tower today.
