Being once a minaret of a mosque, Burana Tower is located near Tokmok in the territory of Balasagun, which was a medieval capital (9th – 14th centuries) of Karakhanid Khanate and home to famous medieval poet Yusuf Balasaguni, author of the poem Kudatgu Bilig (Beneficial Knowledge). The tower was built in the first half of the 11th century. With time, the mosque got completely destroyed, and the minaret was partially ruined by an earthquake in the 15th century. Today, the tower stands at about 25 meters, although it was originally 45 meters tall. An open-air archaeological and architectural museum was created at the basis of the legendary Balasagun.
