Located near the Tokmok town, the Burana Tower is all that remains of old city of Balasagun.

The legend says that once upon a time a beloved daughter of mighty Khan was born шт Balasagun. An old seer told the Khan his daughters future: she would be beaten by black spider at the age of 16. The Khan built the Burana Tower, 40 meters tall to protect his child and ordered to close his daughter inside the tower. On her sixteenth birthday, the Khan went to the tower and brought some fruits with him. A poisonous black spider was among the bunches of grapes. It killed the young princess, so the prophecy came true.
