Burana Tower in Balasagun Kyrgyzstan

Balasagun is in the Chuy Valley between Bishkek and Issyk-Kul Lake. Balasagun was the leading city of the Kara-Khanid Khanate from 999 AD until it was taken by the Kara-Khitan Khanate in 1137. It was then captured by the Mongols in 1218. The Mongols called it Gobalik which means Pretty City.
When I look at the Burana Tower it reminds me of Seljuk architecture. That fits since the Kara Khanid were vassals of the Seljuk. In fact the beginning of the end for the Seljuk began when they lost to the Kara Khitans and the Karakhanids were forced out of Balasagun.
