The abandoned crypt of Laeken in Belgium, is made up of three perpendicular tunnels following the graveyard paths on the surface. Many vaults, both occupied and empty line these tunnels and their inscriptions date from 1885 to 1978. When the crypt was opened, the coffins placed into the underground vault were made of cheap wood. These coffins quickly broke up and liquefied. Because of this the city then required coffins to be made of zinc for the crypt to make them more resistant to corrosion.
