The open-air museum has about 200 constructions. Romulus Vuia designed the Ethnographic Park in 1929. After the Dictate of Vienna (30th of August 1940), the Park moved to Sibiu where it functioned until 1945. In 1956 Teodor Onişor and Valer Butură restructured the Park on four theme sectors: Technical devices and trades workshops; Zonal patterns of homesteads and folk architecture monuments; Ethnobotany (traditional plants, boundary agricultural constructions; Livestock (animal breeding). The first two departments are considered to be essential. The first one takes into account the raw material of the exhibits: wood processing, metal processing and peasant mining; wool processing; ...earth processing; stone processing; agricultural products processing. The second one comprises exhibits from the Transylvanian ethnographic zones. Currently the following ethnographic zones are represented: Maramureş, Oaş, Năsăud, the Transylvanian Plain, Alba Vineyard, the Apuseni Mountains, the Călăţele Depression, Bran, Bistriţa and Gurghiu.
