The paper presents two city-geotourist routes possible to arrange in the northern part of downtown Wroclaw. They allow observation over fifty varieties of igneous, sedimentary, and metamorphic rocks, variations of their textures, mineral composition, colors, etc. More detailed observations show a surprisingly wide range of geological phenomena clearly visible on stone surfaces. Many observation sites allow to present the problems related to the evolution of magmas and the stages of formation of intrusions (streaks, enclaves, vein rocks), or differentiation of metamorphic rocks, depending on the type of protolith and conditions of metamorphosis. Sedimentary rocks, available to observe, show diversity of depositional environments, sedimentary bedding, diagenetic phenomena – such as fossilization of organic remains. Various tectonic deformations, like faults (partly with breccias) or ductile shear zones are also visible. Numerous manifestations of weathering and deterioration (sometimes caused by unusual factors such as long-term use of paving stones, or the bombardment of World War II) are also noted. The proposed geotourist routes allow to show problems of exploitation and processing of block stone, and its application in art (sculpture historical and contemporary). The presented results confirm the great scope for stone materials, used in architectural objects of Wroclaw, as a base for intensive development of city-geotourism. This new form of active recreation can contribute to the innovative promotion of our city, as well as the unusual popularization of the Earth sciences.
