This Gothic church, owned by the Order of St Clare, was built in 1302 on the site of a former monastery. The interior later acquired its ornate baroque decoration. Its dominant architectural feature is its five-sided tower. The attached convent was once a grammar school at which the composer Béla Bartók and the Slovak inventor Jozef Murgaš were educated.
According to legend, the Gothic tower was built by a knight, Christian, out of love for a nun, Matilda. Their love was frustrated by the convent's mother superior, who promised Christian the girl and then reneged on her promise. Today, the church hosts services and concerts. The premises of the adjacent convent are used by the University Library.
