Thomas Didden quarry

The Thomas Didden quarry is a very special part of MergelRijk. The entrance to this part of the quarry was hidden for a long time behind a thick layer of marl. In 2021 we made this quarry accessible to the public.

Time has stood still for hundreds of years in the Thomas Didden quarry. It is as dark as when the Blockbreakers left the quarry 300 years ago. Exciting!

Thomas Didden wrote his name on the wall here in 1706.
If you visit MergelRijk you can now also leave your name in the quarry, just like Thomas Didden did in 1706. This is how you immortalize your name in the caves of Valkenburg.

Cave Workshop

The grotation winch is one of the nicest parts of MergelRijk!

In the cave workshop, tables with the marl blocks and tools are ready for you. You can grab a block here for free and turn it into a nice work of art or souvenir. You start by watching an instructional video, after which nothing stands in the way of a good result.

You can take your own marl creation home with you.

DinoRijk

Dino’s can be found in various places in MergelRijk, but you will find most of them in the part of MergelRijk that we call DinoRijk.

Deep in the cave you will walk around among the large dinosaurs in the cave jungle. You can even touch and cuddle them. And if they’re in a good mood, they’ll even take a picture with you!

Along the way we tell interesting stories about the dinosaurs. Where they lived, how many species there were and which animal was a dinosaur and which was not. This way you will also find out why there are dinosaurs in MergelRijk!
