Märcani Mosque

The Iske-Tash Mosque was built in 1802, supposedly on the site of the mass grave of the soldiers who defended Kazan against the troops of Ivan the Terrible in 1552. In 1830, the mosque was rebuilt in the Classicist style. Closed in the 1930s, the mosque was used as a school and then as a warehouse during the Soviet period. In 1994, the mosque was returned to the believers.

It was named after Kul Sharif, who was a religious scholar who served there. Kul Sharif 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 Siege of Kazan it was destroyed by Ivan the Terrible. The mosque displays several detail through mosaics, ornaments, calligraphy, and more.
Tatar scholars speculate as to whether some elements of Kul Sharif 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 the 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.

The Temple of All Religions or the Universal Temple is a unique architectural complex in the Staroye Arakchino Microdistrict of Kazan, Russia. It consists of several types of religious architecture including an Orthodox church, a mosque, and a synagogue, among others. It is currently under construction since 1992, started by local artist and philanthropist Ildar Khanov. The structure now serves as a cultural center and a residence for Khanov's brother and sister, who both continue to serve as guides and supervisors of the complex.
