Soltan Mosque, Islamic religious building in Kazan, Russia

The Soltan Mosque stands at ulitsa Tukaya 14/4 in Kazan's Old Tatar Quarter, a stone mosque of 1868 built in Tatar-Bolghar medieval traditions with elements of a national variant of Romanesque style. Inside is one hall with an entresol; the three-storey minaret rises over the entry. Its facades were painted red-brown, later green.

Construction of this building was completed in 1868 with funding from merchant Cihanša Ğosmanov, incorporating architectural principles from Tatar-Bolghar traditions. Soviet authorities closed it in 1931, and it remained inactive for more than 60 years until reopening for religious use in 1994.

The mosque is also known as the Eighth Cathedral Mosque and the Red Mosque, after the red-brown colour once applied to its façades, later repainted green. Shigabutdin Marjani, who set the qibla during construction, was given the right to read the first namaz here.

This serves as an active prayer center where visitors are welcome with respect for religious practices. Appropriate dress and awareness of prayer times will help ensure a respectful visit that does not disrupt ongoing community activities.

The first prayer in the mosque was led by Shigabutdin Marjani, who had set the qibla direction during construction. The facades were originally painted red-brown, later green, which earned the building the name Red Mosque.
