The Rev Krzysztof Kluk Museum of Agriculture was built because of the Ciechanowiec Admirers’ Society’s initiative. On the fifth of July 1964 there was an official opening of the Social Museum of Agriculture. It was nationalized in 1968. At the beginning the Museum was situated in an old fire station, and in December 1969 it was transferred to a reconstructed Starzeńscy counts’ mansion in Ciechanowiec - Nowodwory.

Already in 1967, on the mansion’s grounds, had begun the building of an open-air museum – the first object was moved in July – a many-sided wooden manage (riding area) from the town of Usza Mała. At present the open-air museum consists of 44 historic objects (XVIII cent. - XX cent.).

Currently the Museum of Agriculture occupies a 26 ha area, owns two branches: in Drewnow (windmill with a miller’s homestead) and Dąbrowa Łazy (windmill), and eight departments:

• Ethnographic - the oldest department of the Museum, in possession of over 10000 exhibits
