I also got to visit the Özgön Minaret and three mausoleums (a tomb) built for rulers of the Kara-Khanid Khanate. During the Kara-Khanid era, Özgön was an important trade center on the Silk Road and served as one of the capitals of the Kara-Khanid state. The minaret was built in the 11th century, and the mausoleums were built in the early 12th century. The minaret was used to issue the call to prayer five times a day for muslims living in the area. Due to its height and strategic location, it could also be used as a watchtower to protect the town. The Özgön Minaret and mausoleums are also featured on the back of the 50 som banknote!
