In the European space, unburnt clay used as a building material is connected also with traditional Pannonian house in the Central Danube region. With its north-western outskirts, this cultural area reached the territory of the historici Czech Lands - the region of Central and South-East Moravia - and gave rise to Pomoravsko-Panonský /the Morava River Basin and Pannonian Plain/ type of traditional houses). Unburnt clay represents here the basic building material probably as late as since the 18th century, especially thanks to the fire-fighting and civil legislation, inter alia, which restricted the use of timber. In the 20th century, clay was replaced by industrially produced building materials to which contributed both the technical development and the civil legislation which limited and, in the end, fully restricted (1914) the use of unburnt clay. The process of extinction was not proportioned and related to the social and economical situation of village inhabitants in individual regions of Moravia. In the second half of the 20th century, the houses made of clay became old not only physically - a house made of adobe bricks with soil floors in its residential rooms, in the entrance hall for the longest time, became a symbol of obsolete and outdated culture of living. Unburnt clay has experienced certain satisfaction in the Czech Republic since the late-20th century as an environment-friendly alternative that is in opposition to conventional building industry.
