Bohemian Switzerland (Labské sandstones) is a typical erosive formation that was formed after the erosion of a few hundred metres of sea sediments. It belongs to the large bohemian chalk basin that covers much of northern Bohemia and parts of Germany and Poland. The Bohemian-Saxon Switzerlalnd Park itself covers an area of over 700 km2. A unique feature of the area are the deeply eroded sandstone cliffs. In the cliffs are deeply eroded hallos that provide micro climates that give shelter to many alpine and sub-alpine speicies at this low altitude. The park was created to protect these speicies as well as to showcase the unique geomorpholgical articulation of the area.
But the Bohemian Switzerland Park is not only a large area of uninhabited forests and rocks. A major subject of preservation is the cultural scenery. It is a region that has been used by people from pre-historic times An important goal of the park is to preserve and protect the architecture and art of the region.
