Radotínské skály, natural monument in Prague, Czech Republic

Radotínské skály is a 28.3-hectare natural monument on the northwest edge of Radotín, in Prague 16. It consists of three separate parts with abandoned quarries; the largest is the steep Šikmá skála wall above the Lochkov cement works, covered by a layer of cement dust.

Radotínské skály was declared a natural monument on 1 September 1988 by the National Committee of the Capital City of Prague, in IUCN category III. The abandoned quarries and rocky outcrops form an almost continuous geological profile documenting the development of the Prague Paleozoic basin from the uppermost Ordovician through the Silurian to the lower Devonian. In the early 1990s dust from the adjacent Lochkov cement plant was removed and species richness began to recover markedly.

The abandoned quarries and rock faces yield fossils of brachiopods, bivalves, gastropods, cephalopods, trilobites and graptolites. The name Radotínské skály simply refers to the rocks above the Radotín district, and the site lies in the Radotínsko–Chuchelský háj nature park.

The site is easily reached from Radotín via marked hiking trails and offers multiple entry points. The paths are clearly marked and connect to other walking routes throughout the surrounding area.

The area hosts specialized wildlife including heat-loving insects, birds, and reptiles that thrive in the rocky habitats. These species have adapted to the specific conditions found at different elevations across the site.
