Referring to Sword Lake, people will immediately think of Turtle Tower. It is a small tower located in the middle of the lake. The tower is located on a piece of land with an area of ​​​​about 350 square meters. At first glance, we can see that the Turtle Tower has a slightly European architecture. The tower has 3 floors. The higher you go, the smaller the floors become. Although small, but located in a unique location, Turtle Tower is always a place that visitors look to when coming to Hanoi. Ever since I was a child, I have often read and heard stories about this tower. During the day, the Turtle Tower looks somewhat ancient and mossy, but when it is dark, the lights come up again making it shimmering and fanciful. Turtle Tower has been with the people of Hanoi through many storms. This place is the pride of the children of the capital. In short, no matter how far we go, we will always remember this place.
