The palace was an element of the entire farm complex established in the 17th century. The owners were the von Selchow family. The palace was expanded at least three times in the period from the mid-17th century until 1900. It is a large building on a rectangular plan, two-storey, with a basement and an attic. A tower was added in the north-western part. After the war, the palace was managed by the local State Agricultural Farm. Currently, the palace is in private hands. The new owner of the building secured the palace from devastation by replacing the roof covering in 1997, but did not complete the renovation.

The House of the Saint John is the building with the oldest history in the city. The first mention of it dates back to 1351. The current building is much younger. It was built at the turn of the 18th and 19th centuries on the foundations of an earlier half-timbered building. After the secularization of the Saint John order in 1810, the building passed into state hands. It served residential purposes, and after 1945 it housed municipal apartments. In 1978, the building was abandoned and fell into ruin. In 2008, the building underwent a major renovation, which significantly changed its appearance. Currently, it houses the Centre for Polish-German Cooperation.

"Old Castle" is just a colloquial name. Architecturally, the building is a palace and it was originally designed as such. The palace was built in 1812 on the site of the "Red Court" and had features of the classicist style. The founder of the residence and the adjacent park was Adolf Friedrich IV von Waldow. In the 19th century, the palace belonged to representatives of the combined von Waldow and von Reitzenstein families. In 1865, Karl Friedrich Ernst Edward von Waldow und Reitzenstein transformed the estate into an ordination (majorate). His successor, after partial destruction in 1846, expanded the palace in the second half of the 19th century. In the 19th century, a new eastern part was added, adding a representative, monumental façade, which from then on housed the main entrance to the building. After World War II, the building was used as a school, then a sanatorium. Currently, this beautiful building is deteriorating, renovation works have been suspended.
