The construction of the temple began around 1328. The earlier church dedicated to Saint Nicholas, located on the site of the former hillfort at Rega river, then became too small. The new temple was erected in the northern quarter of the new town in the immediate vicinity of the market square and the town hall, on the bank of the escarpment, gently sloping towards the river. Building was conducted in three stages, starting traditionally from the chancel. Major work was completed around 1370. Since the 16th century the temple was a Protestant church. In the years 1865-1867 it was reconstructed and regothisated. After World War II, it became a Catholic church again. In 1986 renovation work was carried out.
At the turn of the fourteenth and fifteenth centuries the church was given the form of a three-nave hall with a separate chancel, a western tower and a vestry. The presbytery was built on a square plan ended from the east by three sides. His slender body was trimmed with buttresses and filled with gothic windows with lancet shape. The interior was covered with a rib vault. A communications turret was erected at the site of the south wall of the chancel and the eastern wall of the southern aisle.
In the second stage of construction, a rectangular nave has been erected with dimensions of 57.8 x 24.2 meters. It had the form of a three-nave hall. Naves were founded on three pairs of octagonal, smooth pillars and two pairs of semi-pillars. Pillars support stellar vaults and roof rack. Perimeter walls have large three-sided, pointed windows. At the south-west corner, a six-sided communication tower with a conical, brick helmet was located. On the east side, the nave is topped with a triangular gable, which is separated by narrow, lancet blendes.
In the last stage of the temple construction a tower was erected. It was set on a plan of a rectangle, adjoining to the nave. The first floor, which is equal to the height of the aisle, houses a great porch divided into three bays. Each of them is closed with a stellar vault. On the axis of the tower, over the portal is a large window with profiled, pointed jambs. Also on the north and south sides are windows with identical appearance. The second floor is a square tower, which is a bell tower. All facades of this floor are decorated with pointed blendes with tracery fill. Some of the blendes are slot holes, through which the sound of bells is extracted. This floor is completed with a platform from which the last floor of the tower grows.
