Citânia de Briteiros is one of the most significant Iron Age hillforts in the Iberian Peninsula, established around the 2nd century BC. Located on the summit of Monte de São Romão, it preserves the structural layout of a fortified settlement covering approximately 24 hectares. The site features stone-walled dwellings, defensive walls, and complex water management systems. Excavations led by Francisco Martins Sarmento in the late 19th century first brought the site to international archaeological attention. The site displays the transition between local Castro culture and Romanization influences. Archaeologists have identified over 150 circular or oval stone dwelling foundations. It remains an active site for ongoing research managed by the Sociedade Martins Sarmento.
