3 Architectural forms of village homesteads in the compact area settled up to 1945 by German-speaking inhabitants called Vyškovský německý jazykový ostrov (Wischauer Sprachinsel Vyškov region German language island) Formation of the language island occurred from the 14th century onwards, in connection with ecclesiastical manors. Due to the conservatism of the German-speaking inhabitants, the form of the house from the first third of the 18th century was preserved in these villages. In the surrounding Czech villages had disappeared by the end of the 19th century.

24 Clay mound architecture ( opus spicatum )

25 Archaic technology process of building not very known. Oldest buildings have single mounds different sizes and pattern of fishbone is not very clear. It seems, that wall was made just from wet clods. Later were single mounds prepared from clay, straw and dung. They were put into walls wet and pressed to wall. It glued them together. Fishbone pattern is clear. Barns were usually made by this technology.

26 This technology was used also for walls outside serving like fence or wall against water by floods. It was also found in some houses, but mainly are in barns

27 Whole barn was made at the same time. Thickness of walls was 500 mm, layer made in one day was high 0,5 m. After certain wilting was made second layer. Whole barn was made in 7 days. 6 days walls, 1 day (or more) roof.
