This church on Március 15. tér has a long and eventful history. Destroyed during the Mongol Invasion and rebuilt in Gothic style, it was used as a mosque during the Ottoman period before being re-rebuilt, after a fire, in Baroque style. It has many remaining elements illustrating its long history, such as a fresco of Virgin Mary from the Anjou period (14th century) and Roman remains revealed to the public in 2017. During that renovation, the organ was also revamped, the same instrument that Franz Liszt played during the time he led the choir here. To take advantage of the great acoustics, the church still holds concerts.
