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.

Since 1962, the Gizi Bajor Actors' Museum, which belongs to the Hungarian Theatre Museum and Institute, has been a unique site for the memory of the Hungarian theatre history. The permanent exhibition, opened in 2010, on the first floor of the museum, preserves the memory of the one-time owner of the villa, Gizi Bajor, one of the biggest actresses of the Hungarian stage: her memorial room displays her personal objects, stage props, while the visitors can get to know the details of her professional and private life.
