Porphyry granite. A rock of igneous origin. Porphyry granite can be called because in the smaller rock mass consisting of feldspar, quartz and biotite crystals, larger (up to 1-1.5 cm long) regular (rectangular) feldspar crystals are visible. The rock was not deformed. The surface of the feldspars is white due to weathering (cooking with clay minerals). Dragged by people from elsewhere and placed at a crossroads.
