The Jezuietenberg is a marlstone quarry in the southernmost part of the Netherlands, near the city of Maastricht.
The quarry has been exploited between 1704 and 1880.
Traditionally Maastricht housed a school for Jesuit priests. Its students would enjoy their free afternoon on wednesdays by retreating into the cave, to find silence and relaxation, as one would suppose.
These weekly trips toke place from 1860 untill 1960, and a hundred year of wednesday-afternoons in the cave somehow has resulted in all kinds of creative activity.
The walls have been decorated with hundreds of pictures in black-and-white and in colour, and the cave was graced with all kinds of reliefs and sculptures, themes ranging from the Alhambra (picture above) to Buddha and to "Egyptian" representations.
In 1967 the Jesuit school has left Maastricht. The quarry got a monumental status in 1966 and has been cared for since 1968 by the Jezuietenberg Foundation. It can be visited by the public, which obviously is not allowed to add drawings or sculptures itself.
