The monastery and the church have been built in the 13th century. According to so far investigated historical data, the Franciscans' church of the Holy Spirit would be the oldest (partially) preserved church in Požega.
Upon the arrival and taking over of Požega by the Ottomans in 1537, the convent was battered down, and the church turned into a mosque called “Šerklot”. Due to that, the church still contains some elements of Late Romanesque, Gothic and Turkish architecture.
Beneath the church shrine, there is a crypt which had been closed in 1867. Next to the Franciscans, famous people of Požega were buried in there like Fra Luka Ibrišimović, the famous “Hawk”- liberator of Požega, and this part of Slavonia, the exalter of Turks, who also found his final resting place here.
