It originally consisted of a multi-storey palace, a terrace, a courtyard and outbuildings. The Konopka family sold the palace to the Austrian authorities, which turned it into a mine building. It then served as a housing for families of saline officials. In the mid-20th century it housed the Municipal Public Library. The building, carefully restored and renovated, was intended for the Małopolska-Świętokrzyskie branch of the Polish Institute of National Remembrance (IPN).
