The Jankay Collection and Contemporary Art Gallery was first opened in 2003. From 2013 it works as part of the Munkácsy Museum on a new location and under a new name - Jankay-Kolozsváry-Tevan Collection .

The history of Hungarians and other ethnic groups, Serbs, Romanians, Slovakians and Germans, living in symbiosis in Békés County began in 1715 when the reorganization of the county took place. In the second half of the 17th century, the county became unpopulated due to fights in the region. The lord Harruckern János György organized the settling of people to make the territory valuable again.

The Pro-Natura permanent exhibition upstairs deals with the flora and fauna in Békés County, mostly by slides. Fossils represent geological past. The visitors can also read interesting writings about Hungarian naturalists.
