The Matthias Church. The first church on the site was founded by Saint Stephen, King of Hungary in 1015. This building was destroyed in 1241 by the Mongols; the current building was constructed in the latter half of the 13th century. It is named after King Matyas (Matthias) who expanded it in the 15th century. He was married twice in the church. The church was the scene of several coronations, including that of Franz Joseph I in 1867 and Charles IV in 1916 (the last Habsburg king). From 1541-1686, during Turkish occupation, it was the city's main mosque. It was heavily damaged during World War II when it was used as a camp by the Germans and the Soviets. It was then repaired and renovated between 1950 and 1970.
