During the second half of the nineteenth century, geology was added as a topic taught at schools of higher education in central Europe. As a consequence, teachers had an interest in finding practical methods to make theoretical knowledge more interesting to their pupils. Pedagogic tools included fieldtrips which could be logistically challenging, and the so called ‘geology walls’ and other stone structures, such as ‘geology pyramids’. These solidly built structures erected from various types of rocks, were put together to simulate the complexities of the underground geology from the lowlands to the mountains of certain geographic areas and may be considered to represent precursors of modern geoparks. Many of these ‘geology walls’ built in several central European cities are preserved and may still be used today to explain and discuss geoscientific phenomena. The fruitful interactions between teachers and pupils, and scientists and amateurs, are topics of this paper. Questions of restitution and international relationships are touched on as well.
