Follow the path on Hammerberg – and travel back 370 million years.

Once, there was a tropical sea here, where fine sediments settled on the bottom. Over thousands of years, it solidified into limestone – a rock that still preserves fossils from that time: shells, crinoids, and armored fish.

Thousands of years later, the mountain became a workplace. People tunneled into the rock, mined ores, and used the stone for houses and paths. After the end of mining, nature reclaimed the area: forests grew, moss covered the rock walls, and bats moved into old tunnels.

Today, the route leads through a unique landscape – shaped by water, influenced by humans, and reclaimed by nature. In the bright, rough layers of rock, one can still sense the sea that roared here long before there were forests.

  • Two hikers walk along a path beside a small creek in a forest. The trees are green and the sun is shining.
