Camp Westerbork was a World War II concentration camp in Hooghalen, ten kilometers north of Westerbork, in the northeastern Netherlands. Its function during the Second World War was to assemble Roma and Dutch Jews for transport to other Nazi concentration camps.
Each single stone represents a single person that had stayed at Westerbork and died in a Nazi camp.
In the 1970s the camp was demolished. Near the site there is now a museum, and monuments of remembrance of those transported and killed during World War II. The camp is freely accessible.
