The small, one-nave Baroque church was founded by Anna Zamoyska, née Gnińska, the wife of the fourth Entailer Marcin Zamoyski in 1696 and designed by Jan Michał Link. The adjacent three-winged convent was built between 1769 and 1774 and founded by the seventh Entailer Jan Jakub Zamoyski. St. Clare Sisters did not have a chance to use their convent for too long; after the convent was dissolved, the building was taken over by Franciscan monks and then by the Sisters of Mercy. In 1817 the building housed a military hospital. Between the two wars it was a seat of the police and after WWII in 1985 an orphanage was moved here.
Since 2010 the building has housed the Karol Szymanowski State Music School of the First and Second Degree.
