The first brick mansion in Staromieście was probably built in the second half of the 18th century by an unknown architect. In the mid-19th century, the mansion was surrounded by a small park and bordered on the north and west by farm buildings. The area of the park varied as new areas were successively added to it. In 1878 the Staromieście estate, together with Miłocin and Ruska Wieś, was purchased by the Jędrzejowicz family and remained their property until 1944. In the same year the Jędrzejowicz estate was taken over by the State Treasury. The park with the palace, was handed over to the local cooperative , “Jedność”, which carried out horticultural production in the transferred facility, while in 1954 the area of the former manor-park complex was handed over to the hospital.
