Castros (Spain)

A castro is a fortified settlement, usually pre-Roman, some from late Bronze Age and Iron Age, associated with Celtic culture. These are frequently found in Northern Spain, particularly in Asturias, Galicia, Cantabria, Basque Country and the province of Ávila, with the Castro culture and on the plateau with Las Cogotas culture.

The word castro comes from the Latin castrum, which means "hill fort".
