Fluweelengrot, Underground quarry and mining museum in Valkenburg aan de Geul, Netherlands.
The Velvet Cave features an extensive system of underground corridors with intricate wall carvings, sculptures, and historic murals etched into marlstone walls.
During World War II, the cave provided shelter for local residents and American troops, while in medieval times it served as a strategic escape route from Valkenburg Castle.
The marlstone walls contain numerous inscriptions, drawings, and sculptures that reflect the artistic expressions and daily life of miners through different periods.
The cave maintains a constant temperature of 12 degrees Celsius throughout the year, requiring visitors to bring appropriate warm clothing for their exploration.
The underground network includes a French period chapel and hidden passages that knights used for surprise attacks and supply transportation during medieval sieges.
