The article is an attempt to form the architectural and urbanistic analyze of the specific Baroque design technique, used for the façades of monumental buildings. For the first time this method was used in its Roman creations by Francesco Borromini. Hence, most often in the literature appears under the Italian designation parete ondulata. It was a difficult concept in both terms – architectural and aesthetic values. It required design skills and construction experience. Prediction of the ultimate effect of the impact inside the urban interior had to be based on an extensive knowledge of perspective or design experience. The spectators probably often did not understood the essence of the solution. This explains relatively small spread of the method in full its extent. Imitation was mostly limited to application of wavy line of cornices or whole façade, which currently in circulation awareness connects with the architecture of the Baroque. Such reception sometimes overrides all huge intellectual contribution of this era in the field of design. Relatively quickly this technique became widespread in other European countries, in which aclasical forms were adopted. The method of concave-convex elevation gave great opportunities not only in creating attractive architecture, but mainly to design urban interiors with a very sophisticated measures impact on the recipient.
