History, Origin, and the Legend Behind Its Name
Turtle Tower (Thap Rua) is one of the most iconic historical symbols of Hanoi, located in the center of Hoan Kiem Lake (Sword Lake). For centuries, Turtle Tower has been closely associated with Vietnamese history, legends, and national identity. Many travelers visiting Hanoi wonder when Turtle Tower was built and why it is called Turtle Tower.

When Was Turtle Tower Built?
Turtle Tower was built in the late 19th century, around 1884–1886, during the French colonial period. The tower was constructed on a small island in the middle of Hoan Kiem Lake, originally serving as a memorial structure.
Although the tower is not extremely large, its unique architecture and location make it one of the most photographed landmarks in Hanoi.
Architectural Style of Turtle Tower
Turtle Tower features a blend of Vietnamese traditional design and French architectural influence, including:
-
Three main levels with arched windows
-
Stone construction suitable for the lake environment
-
Simple yet elegant design that harmonizes with nature
This architectural combination reflects Hanoi’s transition during the late 19th century.

Why Is It Called Turtle Tower (Thap Rua)?
The name “Turtle Tower” comes from the famous Legend of Hoan Kiem Lake, one of Vietnam’s most important national legends.
🐢 The Legend of the Golden Turtle
According to legend:
-
King Le Loi received a magical sword from a Golden Turtle to defeat foreign invaders
-
After winning independence, the turtle appeared in the lake and reclaimed the sword
-
The lake was then named Hoan Kiem, meaning “Lake of the Returned Sword”
Because of this legend and the sacred turtles that once lived in the lake, the tower was later called Turtle Tower, symbolizing peace, wisdom, and national independence.
Cultural and Spiritual Significance
Turtle Tower is not open to the public, but it remains a powerful symbol of:
-
Vietnam’s historical independence
-
Harmony between humans and nature
-
Hanoi’s spiritual and cultural identity
It is especially beautiful in the early morning or evening when the lake reflects the city lights.
