Julianagroeve Quarry

Between Cadier en Keer and Groeve ’t Rooth lies the Schiepersberg, which extends eastwards in a long narrow forest zone to the road between Klein Welsden and Margraten. There are two quarries here in the Schiepersberg. The Juliana quarry is the largest, the small quarry in the adjacent Koeberg is located in a valuable heathland grassland. Geologically, both quarries are also very interesting. The slope forest is in full development and especially in the spring with its forest flora and numerous singing forest birds it is a pleasure to take a walk there. This can be done on the walking path, partly coinciding with the unpaved country road at the bottom of the slope. Source: limburgs-landschap.nl/natuurgebied/julianagroeve-en-schiepersberg

Limestone mining began in 1938. The extracted limestone was delivered to the Nitrogen Binding Company of the Maurits State Mine in Geleen.
In 1954, extraction was stopped due to the poor quality of the marl.
In 1971, Werner Felder and Peter Bosch discovered a small prehistoric flint industry in the slope between the Koeberg quarry and the Juliana quarry. Part of the slope was then excavated to make room for a narrow-gauge railway.
In 2011, the quarry became a nature reserve and owned by Het Limburgs Landschap.
