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 millennial town of Sopron has had centuries old connections with mining even before the opening of our museum. Mineral coal was first discovered in 1753 in the historical Hungary, in the woods around Sopron in the area, which is now called Brennbergbánya. Here the coal was started to be used for industrial purposes with very good results until 1951. In 1920, The School of Mining and Forestry that was transferred here from Selmecbánya according to the "Decision of Trianon" started to function in Sopron.
