Grotwoning De Kluis, Underground dwelling in Sint Pieter, Netherlands
The limestone cave dwelling features multiple chambers carved into the northwestern slope of Sint-Pietersberg, adjacent to the Slavantebos forest near Maastricht.
From 1680 onwards, Grotwoning De Kluis served as a residence for hermits, with Brother Nicolaes and his companions being among the first recorded inhabitants.
The cave system represents centuries of limestone mining traditions in Maastricht, where extracted materials contributed to construction projects across the Netherlands and Germany.
The entrance remains sealed for safety reasons while maintaining small openings that allow local bat populations to use the space for roosting.
During World War II, this underground space protected over 750 Dutch paintings, including Rembrandts works, from potential destruction during the conflict.
