Lake of the Returned Sword Frequently Asked Questions and Useful Information for Travel

Why is it called the Lake of the Returned Sword?

The Lake of the Returned Sword gets its name from a captivating legend dating back to the 15th century. During a period of Ming occupation, a fisherman discovered a sacred sword in the lake. This sword was instrumental in the Lam Son uprising, led by Le Loi, who eventually became emperor.

What is the legend associated with the returned sword?

The legend of the returned sword tells of Le Loi, a national hero, who was gifted a magical sword by a divine turtle from the lake. After successfully leading the Vietnamese army to victory against invaders, Le Loi returned the sword to the turtle, and it vanished into the lake's depths, giving the lake its symbolic name.

Is there a historical account of a child finding a medieval sword in a lake?

While a notable discovery was made in Sweden in 2018 where an 8-year-old found a 1,500-year-old Iron Age sword in a lake due to drought, the legend of the Lake of the Returned Sword specifically involves a fisherman finding a sacred sword gifted by a divine turtle, not a child discovery. This legend is central to the history of Vietnam.

What makes the Lake of the Returned Sword significant?

The Lake of the Returned Sword is more than just a scenic spot; it is a profound symbol of Hanoi's rich history and vibrant culture. Iconic landmarks surrounding the lake, such as the Turtle Tower and Ngoc Son Temple, further enhance its historical and cultural importance, making it a must-visit destination.
