July 4, 2026, Wohlverwahrt Iron Ore Mine (Eisenerzgrube Wohlverwahrt)

The former open-cast mine of the Kleinenbremen mine can be visited and is even part of the marked mining educational trail. From here, you can also enter the underground tunnels with a guided tour.

The Oberberg fissure in the Weser Uplands is a narrow, natural crevice in the limestone of the Oberberg mountain and is one of the region's geological features. It lies well hidden on a steep slope and resembles a deep, inaccessible crack in the rock less than a cave. Due to its narrow structure, slippery limestone walls, and partially unstable floor, hiking guides advise against entering the fissure. It is precisely this mysterious yet difficult-to-access appearance that makes it such a fascinating place, best viewed from a distance.

The Kleinenbremen Visitor Mine is a mine located in the Kleinenbremen district of the East Westphalian town of Porta Westfalica. It opened in May 1988 and is located in part of the disused Wohlverwahrt mine in the Weser Mountains. Iron ore was mined from the mine by Barbara Erzbergbau until the 1960s.

The Kleinenbremen Visitor Mine in Porta Westfalica is a fascinating destination for cyclists interested in industrial culture and geological history. In the former "Wohlverwahrt" iron ore mine, which was in operation from 1883 to 1957, visitors can now immerse themselves in the world of mining. The approximately 90-minute tours lead through underground tunnels, past original machinery, and end at the impressive "Blue Lagoon" – a subterranean lake formed by groundwater. A special experience is the ride on the mine train, which transports visitors to the various stations in the mine. The tours are led by experienced miners who provide authentic insights into everyday working life underground. In the adjoining Museum of Mining and Geological History, exhibits such as fossils, tools, and historical documents can be viewed. There are special programs for children, where they can, for example, try out a drill hammer or simulate a blasting operation.

Impressive little cave a little off the beaten track. You have to be careful not to walk past it. But when you stand in front of it, it's impressive to see such a cave and how dark it is inside. Anyone who likes natural phenomena will definitely enjoy this sight. :)
