This place is advertised as Dino's Monstergrot, sometimes as Prehistorische Monstergrot. It seems it was a former limestone mine with an exhibition intended mainly for children, about dinosaurs and prehistoric men. However, there is no current website listing it, and they do not have their own website. The google streetview looks like the entrance is overgrown with weed. Until we get further information we guess this site is closed.
