Lochkovský profil

Lochkovský profil is a national nature monument on the southwestern edge of Prague, stretching between Lochkov and Radotín along the road toward Zadní Kopanina. It's a place where geology and the history of science intersect – home to one of the reference sections for the global stratotype marking the Silurian-Devonian boundary, a turning point in Earth's history over 400 million years ago.

Why does this site matter to geologists?

The protected area covers 38.1 hectares at elevations between 280 and 350 meters above sea level. The terrain is built mainly from exposed Silurian and Devonian rocks that have long drawn the attention of researchers. It is here, in the valley of the Radotínský stream, that the famous "U topol" paleontological site is found, along with a locality tied to the work of Joachim Barrande, one of the pioneers of Czech paleontology. Fossils discovered in the rocks include cephalopods, mollusks, gastropods, trilobites, and graptolites dating from the upper Ludlow stage.

What can visitors actually see there?

The landscape of Lochkovský profil consists of rocky outcrops and steep slopes covered in vegetation typical of rocky steppe habitats. This makes it home to rare and endangered plant and animal species adapted to dry, stony conditions. The site was placed under protection on August 31, 1988, precisely because it combines unique natural plant communities with outstanding geological significance.

Is it worth visiting without a background in geology?

Absolutely – even without knowledge of stratigraphic terminology, visitors can appreciate the raw, rocky landscape and the quiet atmosphere of a place far removed from the bustle of central Prague. Nature lovers can observe rock-steppe vegetation, while walkers will enjoy a scenic route along the stream valley.

How do you get to Lochkovský profil?

The reserve lies to the west and southwest of Lochkov, on the northern side of the road connecting Radotín with Zadní Kopanina. Although administratively part of Prague, the area has a distinctly rural, natural character that contrasts sharply with the city center's built-up landscape.
