Located in the Hast Imam square, right next to the Teleshaykh Mosque, this library museum houses a number of rare and ancient books. The gem of the collection is the Osman Koran, the oldest Koran in existence (written in the late 7th century). It was commissioned by the third Caliph, Uthman, in order to create a standardized version of Islam's holy writings. According to legend, it was most likely brought to Tashkent by Timur, after conquering and looting much of Iraq. The museum is open daily, from 9 am to 4 pm.
