Trichterberggroeve Limestone Quarry

Highlight • Natural Monument

The Trichterberg quarry is located in the forest to the left of the steep Eckelraderweg, between Gronsveld and Eckelrade. Diagonally opposite are dole chambers. The quarry has been designated as a “Geological Monument”. Steep limestone walls with here and there sawn surfaces and a few small corridor remains are the only remains.

Not much is known about the Trichterberg quarry. That is why Peter Jennekens, Kevin Amendt and Rob Habets wrote a source overview for the magazine of the Study Group Underground Limestone Quarries - Natural History Society in Limburg.

Based on this, they cautiously conclude that the origin of the quarry must lie somewhere between the years 1846 and 1867.

These are very old flints, protected in the Natagora site. No fewer than 13 cave entrances follow one another along the path. They are not deep and run along the slope. Chalk was also mined there.

A mysterious flint cave on the edge of the Albert Canal, near the locks at Klein Ternaaien. You reach the entrance via a steep path through the woods. The caves are dark, cool, and full of atmosphere—perfect for those who love hidden natural spaces. Bring a flashlight and good walking shoes!

Very nice walking route along the chateau. Beautiful panorama. With a house in the valley below that used to be the border post.

Neercanne Castle was built on the original site of Roman fortifications, the caves of which still exist and are used as wine cellars. The original staircase with a banister on wide columns is still in the hall. The ceiling features relief depictions of weapon trophies. The castle is currently in use as a hotel and restaurant.

Text board [see photo] Limestone quarry Trichterberg Geological Monument Limestone quarry Trichterberg In the past, limestone was mined at this location. This limestone was used as building blocks and at a later time for fertilizing (oenergelen) fields and meadows ` In the upper Cretaceous (80 to 65 million years ago) the whole of South Limburg was flooded by a 'Cretaceous sea'. Many plants and animals that are now extinct lived in this tropical sea. The limestone visible here consists of countless skeletons of small plants and animals that formed the plankton. Many large animals also lived in this Cretaceous sea, such as the ten-meter-long 'Mosasaur'. Flint Flint is a hard rock that can form in pure limestone under very special circumstances. Flint consists of pure silica (SiO2). In the Stone Age, this rock was used for making stone tools. Until the last century, flint was used to make fire using the Tinderbox.

2025 [see photo] Opened Excursions will start again from 1 April 2025 In this prehistoric flint mine, flint was extracted from the subsurface by our ancestors 6000 years ago to make tools. The raw flint and the tools made from it are found from Northern Germany to the Alps and were of great importance in the Stone Age. Work has been carried out in this oldest industrial monument in the Netherlands for many centuries.
