Natural monuments in Thuringia

The Marienglashöhle is a show cave situated in the Thuringian Forest. While it features natural caverns, it primarily consists of cavities resulting from historical gypsum and copper mining activities. It is thus managed and presented as both a cave and a show mine. This geological site is designated as a geological natural monument. Positioned between the towns of Friedrichroda and Bad Tabarz, the Marienglashöhle is easily accessible. Visitors can find a large parking lot along Federal Highway 88, and there is also a Thuringian Forest Railway named after the cave nearby. Guided tours are avai
