The castle in Rzemień, is part of a fortified complex consisting of a residential and defensive tower and earth bastion fortifications. It is a rare example of medieval defensive construction (15th century) that has survived to the present day. It is situated in a vast landscape park of several hectares, in the northern part of which a classicist palace was located in the 19th century. The tower underwent extensive renovation in the 1930s. A tower with stairs was then added. The castle-palace-park complex was the living centre of the Szaszkiewicz family, displaced from Rzemień by the Germans after the outbreak of war, due to the nearby testing of V2 rockets. After the war, the entire estate was taken over for land reform purposes.
