Parish church of St. Catherine dates back to the turn of the 14th / 15th century. The first mention of it comes from 1448. In 1887, 1906 and 1955 it was renovated, during the 19th century works, the gables of the eastern and western façades were also rebuilt, giving them neo-gothic features.
The church is a modest, gothic building made of brick in the Flemish bond on a stone foundation. The interior is arranged on a rectangular plan, covered with a flat, timber ceiling. From the north a sacristy was added, and from the south a porch. Gables crowning the shorter walls of the building were heavily rebuilt in the 19th century. The buttresses were attached in the corners of the external walls.
