The Legend Behind Hoàn Kiếm Lake Hanoi

The name Hoàn Kiếm lake literally means “Lake of the Returned Sword”, and yes, it comes from a story that still echoes through the city today.

According to Vietnamese legend, Emperor Lê Lợi was given a magical sword by divine forces to fight off Chinese invaders. With it, he successfully drove them out and reclaimed Vietnam’s independence.

But the real twist?

After the war, while boating on hoan kiem lake, a giant golden turtle surfaced and demanded the sword be returned to its rightful owner, the Dragon King. Lê Lợi obeyed, and the turtle disappeared into the depths, taking the sword with it.

From that moment, the lake became hoàn kiếm lake, the place where the sword was returned. And locals still believe that the turtle never truly left.
