The Plzen Historical Underground is one of the largest underground
labyrinths in Europe. It arose during the town foundation in the 13th
century. Tunnels, vaults and galleries with a length over 20 km were
gradually hollowed in a sandstone subsoil in several levels. They
were used for storing food and as an escape way from the town. At
present, a tour with a length of 1 km is open to the public.
