The church of the Assumption of the Blessed Virgin Mary was founded by prince Henry II the Pious in 1238. The construction lasted until the end of the 13th century (from this period comes the western facade of the church with towers), but already in 1240 the church in Lwówek consecrated in the times of Prince Henry I was mentioned. From this period, the western facade of the temple with towers preserved to this day. After burning in 1455, the construction of the current church nave began. It was conducted in the period from 1493 to about 1550, initially by the architect from Zgorzelec Konrad Pfluger, and in the years 1512-1550 with the participation of the builder Hans Lindener. After another fire in 1752, the vaults collapsed, which during an unsuccessful restaurant in 1863-1866 were replaced with a simple wooden ceiling. At the same time, six internave pillars were removed from the interior.
The original church was probably a three-nave building, perhaps a basilica, with two towers at the west facade, made of sandstone. The late romanesque massive western part, the so-called westwork stood out from the nave, with two octagonal towers covered with pointed roofs and a portal from the end of the 13th century, made of red sandstone, with stepped jambs with columns and rich floral decoration.
As a result of the late gothic reconstruction, a new hall, three-aisle nave was erected, without the chancel separated from the external body. On the eastern side, all three aisles were finished polygonal, and the whole nave was strengthened with buttresses. On the north side in the 15th century a rectangular vestry was erected, topped with a stellar vault, and a little later, probably in the 16th century the porch on the west side of sacristy. During this period, a two-bay chapel with stellar vaults was also added from the south.
