St. Mary's Cathedral (Estonian: Toomkirik, German: Ritter- und Domkirche, full name: The Episcopal Cathedral of the Holy Virgin Mary, Tallinn, Estonian: Tallinna Püha Neitsi Maarja Piiskoplik Toomkirik) is a Lutheran cathedral church located on the Toompea hill in the medieval central part of Tallinn, the capital city of Estonia. Established in the 13th century, it is the oldest church in Tallinn and mainland Estonia, and the only building in Toompea which survived the 17th-century fire. The church was originally established in the 13th century as the Roman Catholic cathedral, after Tallinn and northern Estonia had been conquered by the Kingdom of Denmark during the Northern Crusades. In the aftermath of the Protestant Reformation, the church became Lutheran in 1561 and is now seat of the Archbishop of Tallinn, the spiritual leader, and chairman of the governing synod, of the Estonian Evangelical Lutheran Church. The church has been a national cultural monument of Estonia since 20 September 1995.
