The open-air museum is the oldest facility of its kind in Slovakia. It was open to public in 1965. On an area of 1.5 hectares, arranged like a park and garden, there are 24 exhibited buildings, which present the folk culture and the construction of two ethnic groups, Slovaks and Rusyns, living in the regions of Upper Šariš and Northern Zemplín. They come from the 19th and 20th centuries and they typologically belong to wooden constructions of the Carpathian type.
