Built in the years 1378-1402 by Bishop Jan I the Monk as a chapel dedicated to the Blessed Virgin Mary. It was located outside the city walls and was located in the suburbs.
It is a Gothic, single-nave building with an octagonal tower on the west side. Initially, it was connected by a cloister with the castle. In the years 1527-1945 it was an Evangelical temple, where Polish priests worked from 1821. The Polish population, who could not live and trade in the city, came here for services, and hence the name of the Polish Church. The mass was attended by Poles who were not allowed to live nor trade in the town and thus it was named the church.
Currently, it is the place for a Remembrance Chamber – a small museum, exhibiting old machines, tools, furniture, antique coins, military equipment, documents and sculptures made by the local artists. The chamber is open in the summer season (July-August). On the outside, the building has a Gothic look. Its eastern top is an openwork structure with circular openings and three recesses with blind windows and a small window.
The western top wall, however, has four recesses and small twin windows on the sides. Both tops look more dynamic due to the slender pinnacles. Inside, there is a wooden vault from the 18th Century in the Baroque style. The polychromes present Christ as a source of life, with four silhouettes of evangelists on the sides, in the form of medallions. Additionally, on the ceiling there are inscriptions in Polish, German and Latin.
