In Gosławice, in the park not far from the church and castle, until the late 1960s there used to be a small brick manor house, rectangular in plan, with a tiny porch supported by wooden poles. The double-tract building with a vestibule on the axis had a pitched roof with jerkin heads and was covered with shingle. A characteristic feature of the manor was the construction technique of the second-story walls, the so-called 'brick nogged timber wall'. Unfortunately, due to its bad condition, the manor house had to be torn down. In 1863 the manor probably housed a hospital providing medical care to those wounded in the Polish uprising of 1863 against Russia.
A similar manor house was erected in Ruszków near the town of Koło at the twilight of the 18th century. In the second half of the 19th century it was partially renovated. Its square porch got a new look after it was enclosed with walls. A flat-vaulted vestibule thus created had two lancet windows. The alterations allowed to arrange a balcony on the second story.
After the second World War the manor house in Ruszków was converted into a school building. However, when the school was moved to another location, the manor gradually became a ruin.
In 1988 the Provincial Restorer for the Historic Sites and Monuments catalogued the manor's premises. Two years later the building was reconstructed in Gosławice in the grounds belonging to the District Museum. Thus an exhibition area of 400m2 was created. The manor houses the exhibition entitled "The Polish Manor." On the basis of diaries, inventories, and interviews with the elderly remembering the two manors (in Gosławice and Ruszków), the interior of the house was arranged with furniture and decorations dating back to the period between the 18th and 20th centuries. However, the building has no kitchen; it used to be located in the annex which has not been restored.
On the first story there were six rooms arranged in enfilade, namely: a dining-room, a living-room, a study, a bedroom, a wardrobe, and a room for keeping tableware. On the second story all the rooms - a guest room, governess's room, and the landlady's relaxation room - have a separate entrance from the corridor. They were heated with circular tile furnaces. In the living-room and the landlady's relaxation room there are still semi-oval alcoves designed for such circular furnaces. But the two front rooms on the second story - the guest room and governess's room - were heated with a fireplace.
