Mosques have been the spiritual centers of Islam since ancient times. In the ancient cities of Bilyar and Suvar, only walls and basements have survived. The old mosques, a historical and cultural heritage, give a special touch to modern Kazan. The recently constructed buildings also embody the best traditions of Muslim architecture. Nowadays, there are more than 1,000 mosques in Tatarstan. Visitors may admire the magnificent ensembles, indicating the spiritual revival of the people, in all the cities and regions of the republic.
