We had a wonderful hike in the Brohltal in the Eifel. 🥰
One of the many beautiful sights are the trass caves.
🌋 Trass, a volcanic tuff, was already mined there by the Romans. These are the deposits of a volcanic eruption that created Lake Laach around 13,000 years ago.
🏗️🏛️ Tuff is a soft rock that is primarily used as a building material on the outside of buildings or is mixed with cement.
