The Church of St. Mary Magdalene - dating from the mid-thirteenth century - originally served as a parish church for the city's Hungarian citizens; During the first half of the Turkish occupation, the only Christian church remained in the castle, and then during the second half it was converted into a mosque. When the Turks were defeated in 1686, it was returned to the Franciscan Order, which destroyed most of the church except for the tower, and used stones to build a new church in the Baroque style.
