The church of St. Barbara was built in the fifteenth century on the site of an earlier wooden chapel. This chapel, then located outside the city, served as hospital for infectious patients. With time, it was extended to the size of a substantial church, which in 1456 was raised to a parish rank. At the end of the 15th century, the church and hospital were destroyed several times by fires. After another of them, reinforcement buttresses were erected in 1545, and at the end of the 16th century, the tower was rebuilt. In the years 1726-1728, the reconstruction took place, fundamentally changing the character of the church. A narrower and lower southern aisle has been added to the existing gothic building, thus creating a three-nave interior. At the same time, the baroque form was given to the gables, previously decorated with gothic pinnacles. The southern nave was dismantled in 1966 due to war damages, partially restoring its original appearance to the church.
The church from the fifteenth century was a hall, two-nave building, without a chancel separated from the outer corpus, with a tower on the western side. Currently its length is 36 meters and the width is 18 meters. The northern wall has prominent outer buttresses. Two portals lead to interior: the ogive under the tower and the smaller one on the north side. The church is lit with a large, single, pointed arch window with traceries in the east wall and four ogival windows from the north. Windows on the south side are the result of modern reconstruction. The interior is decorated with a diamond vault in the porch under the tower and the groin vault in the chapels between the buttresses. The original vault of the nave did not survive. On the north-east side there is a square sacristy, covered with a diamond vault.
