Qolsarif Mosque - Kazan
Originally, the mosque was built in the Kazan Kremlin in the 16th century. It was named after Qolşärif, who served there. Qolşärif died with his numerous students while defending Kazan from Russian forces in 1552. It is believed that the building featured minarets, both in the form of cupolas and tents. Its design was traditional for Volga Bulgaria, although elements of early Renaissance and Ottoman architecture could have been used as well. In 1552, during the storming of Kazan it was destroyed by Ivan The Terrible.
Tatar scholars speculate as to whether some elements of Qolşärif Mosque can be seen in Saint Basil's Cathedral in Moscow (8 minarets, a central cupola, not typical for Russian architecture). Since 1996, the mosque has been rebuilt in Kazan Kremlin, although its look is decisively modern. Its inauguration on July 24, 2005, marked the beginning of celebrations dedicated to the Millennium of Kazan. It can accommodate 6,000 worshipers.
