ABSTRACT
During the Second World War, a fortified complex was built in the province of Cádiz whose mission was to protect the coastal strip linked to the Strait of Gibraltar. Composed of almost four hundred bunkers along more than one hundred and twenty kilometres, today they remain forgotten and unidentified, in spite of their value as an architectural reference of a turbulent epoch that marked the world event of the second half of the 20th century. Its dispersed configuration introduces a very clear territorial component, where Geographic Information Systems (GIS) is established as an essential work tool. This contribution synthesizes some of the procedures used with GIS tools to understand and record the fortified system on the north shore of the Strait of Gibraltar, and more specifically the complex of machine gun nests and anti-tank gun emplacements: what was constructed in the past; and what presently remains.
