The camp covered an area of about 50 hectares, divided into three sections and surrounded by barbed wire fences.
It was used to house "undesirable" foreigners, in particular, anti-fascist intellectuals and former members of the International Brigades,[1] particularly the more troublesome or senior veterans.
