The geological walk through the center of Oudenbosch takes walkers past buildings and paving with natural stone and fossils. The description showcases “Stone-rich Oudenbosch” and shows the rocks/fossils exhibited in the museum in their context of use. In addition to the Regina building, participants are guided past various other monuments with beautiful natural stones. The “Thunder Stone” at the museum entrance naturally cannot be missed, and there is also attention to the many fossils in ornaments made from Belgian Devonian limestone (Arduin) in Fenkelstraat.
