The interest in folk architecture dates back to the second half of 19th century. The Czechoslavonic Ethnographic Exhibition played an important role, but most projects of preservation of architecture were not carried out. The law from 1958 codified the preservation of settlement wholes; many individual folk buildings were to be preserved as well. Ony after 1989 a positive approach of state authorities towards folk architecture became visible. As early as in 1990, 20 preservation zones were declared in southern Bohemia; in 1995 60 new zones in the whole area of the republic were declared. Besides the approach reffering preservation of individual outstanding objects in their original localities, the method of conservation of some monuments by their transfer to the specialized open-air museums was implemented as well. The largest and the oldest one is the open-air museum in Rožnov pod Radhoštěm.opened in 1925. Other smaller museums of this kind came into being as late as in 1960s and 1970s (in Přerov nad Labem, Vysočina near Hlinsko, Třebíz near Slaný, Kouřim, Strážnice (south-eastern Moravia), Zubrnice (northern Bohemia), Rymice near Kroměříž, and others. Several similar museums are in the state of preparation (Chanovice and Velhartice near Klatovy, Vysoký Chlumec near Příbram). The present legislature gives several possibilities of preservation of folk architecture. The implementation of preservation plans is supported by state subsidies, various local as well as international programmes. and Anglický abstrakt s šifrou (št) je uveden na str. 199-200.
