Ruins of the Wilczewski manor house from the 17th century in Wesołówka, with the remains of a moat, earthen terraces and a complex of buildings. As a result of military operations during the January Uprising (the Battle of Stanin on March 14, 1863), the manor was seriously damaged and the estate was divided as a result of the enfranchisement reform. The last owners of the estate were the Pac-Pomarnacki family. The property was confiscated from them on January 4, 1951, by order of the Presidium of the District National Council in Łuków.
