Notable cathedrals and churches include the Gothic St. Martin's Cathedral built in the 13th–16th centuries, which served as the coronation church of the Kingdom of Hungary between 1563 and 1830. The Franciscan Church, dating to the 13th century, has been a place of knighting ceremonies and is the oldest preserved sacral building in the city. The Church of St. Elizabeth, better known as the Blue Church due to its colour, is built entirely in the Hungarian Secessionist style. Bratislava has one surviving functioning synagogue, out of the three major ones existing before the holocaust.
