Bolghar

Bolghar was intermittently capital of Volga Bulgaria from the 8th to the 15th centuries, along with Bilyar and Nur-Suvar. It was situated on the bank of the Volga River, about 30 km downstream from its confluence with the Kama River and some 130 km from modern Kazan. The city is supposed to have been the capital of Volga Bulgaria from as early as the 8th century.

Today, the capital of Tatarstan is Kazan, but many Tatars consider Bolghar to be their ancient and religious capital and to allow a glimpse of Muslim Bulgar life before the Mongol invasion of Volga Bulgaria.
