Kosoř: Nature, Geology and History

Kosoř lies in the Český kras Protected Landscape Area. Two distinct focuses can help you choose it as a destination: the geological and ecological significance of protected landscapes, and historical buildings and memorials. A nature trail also ends in Kosoř, at a viewpoint overlooking Černá rokle.

Nature and Earth’s history around Kosoř

The Černé rokle National Natural Monument lies between Kosoř and Radotín and also includes areas within the cadastral territory of Kosoř. Its international geological and palaeontological significance is reflected, among other things, in a stratotype profile for the boundary between the Lochkovian and Pragian stages. Such a profile serves as a reference point for defining geological stages—a specialist feature for anyone interested in Earth’s history as well as the landscape.

The natural monument includes rocky steppes, steppe grassland and disused quarries. These habitats are distinguished by remarkable flora, bryoflora and mycoflora—that is, moss and fungal flora—as well as a rich insect fauna.

Another geological point of interest is the Radotínské údolí Nature Reserve (PR). It extends south to Kosoř and includes areas within its cadastral territory. The area is known for its internationally significant geology and several classic fossil sites. While Černé rokle has a specific stratigraphic feature in its stratotype profile, the fossil sites are also a focus at Radotínské údolí.

The Klapice Nature Reserve (PR) is also near Kosoř: a steep, wooded spur with several disused quarry faces.

Cultural monuments and local history

The Chapel of Saint Anne in Kosoř is an immovable cultural monument. It was added to a modernised manor house in 1722. The chapel has two bells dating from 1723, one larger and one smaller. The construction date and the year of the bells therefore follow one another closely; the two dates provide a specific time reference for this monument.

Another cultural monument is the statue of Saint John of Nepomuk. It was erected in Kosoř in October 1895 and is listed as a national cultural monument. Together with the chapel, it shows that the area’s historical points of interest are not limited to a single building.

The name of the village also has an early historical record: around 1310, Kosoř appears indirectly in written historical sources, in the byname of the nobleman Valter of Kosoř, Walterus, miles de Cossor. This provides a historical timeframe without treating the date as the year the village was founded.

Nature trail and planning your visit

The Kosoř–Černá rokle nature trail ends in Kosoř on Dolejší ulice, at a viewpoint overlooking Černá rokle. If you include the nature trail in your plans, check its current condition before your visit.

When choosing where to stay, you can weigh the different highlights according to your interests: the protected areas offer geology, fossils and distinctive habitats, while the chapel, bells, statue and historical record of the village’s name offer connections to local history.
