The Zemplín museum in Michalovce was founded in 1957 as the Zemplín museum of local history, and since 1965 it has been operating under its current name. The museum's collections and exhibits are located in the premises of the baroque-classical mansion of the nobles from village Staré and city Michalovce. The mansion was created in the 17th century by rebuilding an older castle. The Zemplín Museum documents living and non-living nature as well as the overall cultural-historical and economic development of the Zemplín region.
