The 20th century permanent exhibition dealing with the most important artists and aspirations until the end of the Second World War is located on the recently renovated second-floor of the museum. The time period we concentrate on is 1896 to 1945, with 150 paintings, 30 statues and 200 coins.

The monument building of the museum stands near the town center, under house number 11 Dózsa György Rd. On its classicist front wall, above the wrought iron gate, there reads the year of its building: 1827. During the reform era the Zemplén Casino Society operated here, which gathered the progressive intellectuals of the county and the town. The building served as the local council between 1894 and 1950. The museum moved to its present place in 1990.
