The Klokočské skály (German: Klokotscher Felsen ) are a sandstone rock area near Turnov in the Bohemian Paradise . The 228.13 hectare area has been designated as a nature reserve since 1985 .
description
The Klokočské skály are a clearly visible rock bar about 60 meters high and 1600 meters long above the municipality of Klokočí , about four kilometers northeast of Turnov.
Only a few rock towers were split off from the compact sandstone slab. Worth seeing rock towers are the Krug ( Džbán ) and the town hall ( Radnice ). The rounded rock formations are also called elephants.
The compact rock ledge is heavily hollowed in places. The most famous of these excavations is the Postojna Cave , also known as America , in the Zelený důl valley .
The northernmost part of the rock group is called Betlémské skály ( Bethlehem rock ). There are also numerous caves in it. Main attractions are the Klokočské Průchody ( Klokotscher Labyrinth ) and the ruins Rotštejn ( Rothstein ) in the southern part of the area. This rock castle dates from the 13th century and, as was customary at the time, was mainly built of wood. Only the rooms, wells and parts of the wall carved into the rock have been preserved from the castle. It was built by Jaroslav and Havel von Markvartice - the founders of Turnov.
geology
A special feature of the Klokotsch rocks is the concentration of many geomorphological sandstone forms in an area of only 3 km². The rocks are made of Turon sandstone ( Upper Cretaceous ). They are located near the Lusatian Fault and were always on the edge of the sedimentation basin . These conditions meant that the deformation of the boulders was inhomogeneous. In addition to faults and sloping sediment layers, the area is particularly characterized by concretions . The spherical structures with a diameter of up to one meter were the least resistant places in the rock and thus the most exposed to weathering. The remains of concretions that were opened, cleared by animals or washed out by rainwater have remained as cavities or caves in the rocks and give them their characteristic shape today.
