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

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. The entire PDF with all sources can be found at https://www.sok.nl (November 2013 edition).
