"The sky in the Brohl Valley darkened as the Laacher See volcano erupted just five kilometers away. A blazing-hot mixture of lava particles and gases shot into the atmosphere at intervals. Each time the eruptive column collapsed, the material raced through the surrounding valleys as if on a cushion of air – ash and lava particles filled the valleys up to 60 meters high. The once loose materials of the pyroclastic flow have, over time, baked into a rock known in our region as "trass." The Romans already mined trass in the Brohl Valley and used it, among other things, for house construction. Finely ground, with the addition of lime and water, it produces a mortar that hardens even underwater. It is likely that it was the Dutch who promoted mining in the Brohl Valley since the 16th century, as trass is ideal for building dikes and harbor facilities. They were also the ones who gave the volcanic cement its name: "Tyrass" is Dutch for "glue." The trass walls you see from here have been hollowed out by mining and can be visited. Due to their poor quality, they were no longer of interest for mining and today are an impressive testament to the massive pyroclastic avalanche that once filled the entire valley.

Nice path through different caves / passageways. The Trass caves are a great experience for young and old.

13,000 years ago, the Lacher See volcano erupted, so this rock was created. At that time, the Romans cut off large blocks of trass and shipped them across the Rhine to Italy. In the 1800s, trass was mined and processed into a kind of cement in the mills. Today you can see these caves.
