The church of the Immaculate Conception of the Blessed Virgin Mary in Dzierżoniów was probably founded in the 14th century as a monastery temple of the Augustinian Order. Its founder was the bishop of Wrocław, John, who brought monks from Nysa. The chancel was erected in the first half of the 14th century and the nave in the second half of the 14th century. In 1525, Augustians, leaving the town, sold the church. In the following centuries, it was used by Protestants.
The church was built of stone and brick in the gothic style. Originally it consisted of an orientated, rectangular nave and elongated chancel with a three-sided closure. The presbytery has buttresses and is covered with a gable roof. On the south side there is a two-part sacristy from the 16th century.
