The San Simón archipelago is made up of four islands dedicated to four saints: San Bartolomé, San Norberto, San Simón and San Antonio. These last two are the ones that host the facilities. The history of the island is long. In the Middle Ages, a community of monks settled and it was one of the leading spaces of medieval Galician poetry, of such splendor in the Europe of its time. Pirate attacks (especially the one carried out by Sir Francis Drake) turned the space into a constant witness of battles. In 1702 the famous Battle of Rande took place between the Anglo-Dutch and Spanish-French teams, with victory for the former. In more recent times, the island was a pesthouse until during the Civil War it became a concentration camp. Around 6,000 political prisoners passed through it. In the second half of the 20th century it was a hospice and a recreational space. Currently the island rehabilitated the facilities, which are used for socio-cultural activities, from congresses and conferences to music schools or camps.
