Geological wall at Botanical peoples park Blankenfelde-Pankow, Geological teaching wall in Blankenfelde-Pankow, Berlin, Germany

The geological wall at Botanical peoples park Blankenfelde-Pankow displays rock specimens from different German regions arranged side by side in an organized fashion. Each sample is labeled and shows the different types of stone found beneath the surface of Central Europe.

Eduard Zache, a Volksschule teacher, designed the wall, built 1891–1895 in Volkspark Humboldthain. In 1912 it was moved to the Botanische Anlage Blankenfelde. In 2018 the Technische Universität Berlin and the Verein der Geowissenschaftler in Berlin und Brandenburg cleaned and largely restored it. It holds Nationaler Geotop status.

The geological wall functions as an open-air educational resource where students and visitors learn about the structure of Central European earth crust.

The site is freely accessible and each stone carries detailed information that allows visitors to explore the collection at their own pace. The best time to visit is during good weather when the rocks display their colors and textures clearly.

The wall was designed by Volksschule teacher Eduard Zache and first stood in Volkspark Humboldthain from 1891 to 1895 before being moved to Blankenfelde in 1912. In 2018 the Technische Universität Berlin and the Verein der Geowissenschaftler in Berlin und Brandenburg cleaned and largely restored it.
