Large Dual Purpose Rock Installations in Norway in Peace Time: Recreational Facilities in War Time: Civil Defence Shelters

Norway, a country large in area but small in population, has put large effort in protect- ion of its inhabitants in case of war. The Civil Defence has provided shelters for more than 50% of the population. Some of these shelters are put into rock. Since rock installations give large resis- tance against weapon effects and also by advan- tage can be used for several purposes in peace- time, an interesting development has taken place the last decades. In towns and cities you will find sport halls, swimming pools, bowling and shooting ranges etc in rock, which easely can be conver- ted to civil defence shelters. Some typical installations are highlighted in the following.
