The efforts and results of the research work of the 19th-century personalities who prepared the Czechoslavic Ethnographic Exhibition was continued by other scientists from ethnography and other disciplines dealing with folk culture in the 20th century. Dušan Jurkovič, Zdeněk Wirth and Václav Mencl as well as others were among the most significant experts in the branch of vernacular architecture. Antonín Kurial, a student of Prof. Groha and a university teacher, followed their traces and learned from their results. He succeeded in developing the theories about the documentation of vernacular architecture into a fully- fledged practice. Together with his students at Brno University of Technology, he tried to achieve the best possible way of documentation. After World War II, he started to make an inventory of and to localize more than 1 300 buildings and to survey the selected vernacular buildings from Moravia and Silesia in the measuring scale 1:50 and 1:25. Eastern Moravia, especially the regions of Luhačovské Zálesí and southern Wallachia as well as the villages with timbered architecture in the Vsetín area are abundantly represented in his collection prepared for the Atlas of Vernacular Architecture. The collected documents are published in the form of a printed Catalogue of Vernacular Architecture in particular districts and they are considered to be a unique form of detailed documentation of vernacular buildings in Central Europe.
