The detailed documentation of large foundation pit near Strahov monastery in Prague made possible to establish the detail section of basal Cretaceous deposits (Peruc Member). Claystones are main representative sediments of the Peruc Member. They contain intercalations of coal and clayey sandstones. Wash-out channel, filled with coarse ferruginous sandstones is cut in the upper part of Peruc claystones. Geodynamic structures – landslides and tectonic zone of horst type were identified. The engineering geological conditions of this respective building site are described.
