It is a National Natural Monument, located at the foot of Dubí Mountain. The subject of protection is the walls of the former basalt quarry, which disintegrates in the so-called loaf way. The wall is up to eight meters high and the individual columns up to a meter thick. In the top parts, some are curved and narrowed.
Protected species of animals also live here, such as the common viper (vipera berus) or the common lizard (lacerta agilis Linnaeus).
