The church was founded at the beginning of the 13th century from the foundation of the local Benedictine Monastery. In the years 1549-56, the church was rebuilt in the gothic style on the initiative of the abbot Paweł Chojnacki. The existing building was raised and a new nave was added from the west. In the 17th century, the western gable was converted into mannerist style. From the beginning of its existence until 1836, the church was a parish church for Lubiń. Then, after the dissolution of the monastery, the parish was moved to the monastery church of the Blessed Virgin Mary, and in 1853 the church of St. Leonard was handed over to the evangelicals. After the Second World War, the church was returned to the Benedictines.
The original romanesque church was aisleless building with a separate chancel, narrower than the nave. It was erected from granite quares, with details such as frieze, window frames, portal, chancel arch and apse arch as well as the edges of the sedilia made of ceramic elements. This shape has not changed to this day except for the western wall, which was pulled down in the 16th century to connect with the nave. At that time, the walls were added over the romanesque part, creating a bell tower. Late gothic fragments were built of bricks. The original chancel was covered by a groin vault, apse by half-dome, and a nave including a added part by a flat timber ceiling.
