The Antarctic Campaign takes place annually in the Spanish Antarctic Base "Gabriel de Castilla", located in Decepción Island (Archipelago of the South Shetland Islands) and in those other places of the Antarctic territory that are determined, all within supporting the Ministry of Science, Innovation and Universities and the Spanish Polar Committee (CPE.) for the development of Antarctic research.

During the 3rd Spanish Antarctic Campaign, the Spanish Army proceeded to the installation of the refuge "Gabriel de Castilla", which was inaugurated on December 20, 1989, and which became ten years later, the Base "Gabriel de Castilla". The base receives its name in honor of the Spanish admiral who in 1603 sailed through those Antarctic waters informing on his return of the sighting of immense snowy lands.

The mission in Antarctica is to contribute to the Spanish presence in the Antarctic area, thus fulfilling the commitments established in the Antarctic Treaty and the Madrid Protocol. An essential support is provided to Spanish researchers and other nationalities, so that they can carry out their work in optimal conditions.
