Immediately next to the Church of St. Lawrence, sits the convent of the Sisters of Mercy of St. Vincent de Paul who have been active in Požega since 1878. The building was built as a one-storey building in 1726 for the needs of the Požega Lyceum. Academia Posegana, which operated from 1761 to 1776, was once situated in this building.  With faculties of philosophy and theology, it mostly aimed at educating priests ordained in the Slavonian part of the Zagreb archdiocese which used to be under the Ottoman rule. After the new building for the Požega Lyceum was built, the Sisters moved into the building of “the old Jesuit Lyceum”.Thanks to the gift of the archbishop of Zagreb, the Sisters founded a civic grils’ school in the jesuit building between St. Lawrence Church and the convent, in the former St. Lawrence Church musicians’ building. During the late 19th century urbanization efforts, a second floor and outbuildings were added to the building. To complement the education they provided, the Sisters built a two-storey building next to the convent to be used as a girls’ homemaker school. This building, together with the convent and St. Joseph Chapel form a unit which can be seen today.
