The Owl Castle


The cliff rising 84 m high near the edge of Šurice village egy is a diatreme, and its upper part is a block of settled sediments from the former maar-lake.

Herrmann M. (1941) was the first to give a detailed description. A tuff-breccia forms the lower part of the cliff, which contains porous basalt clast and sandstone inclusions torn up from the basement. (Konečny et al. 2004).
