Castro de Lobadiz, archaeological site in Spain

Castro de Lobadiz is a coastal hillfort on a peninsula at Punta del Castro, between Doniños and San Jorge beaches in Ferrol. Its defences are concentric: two walls with a ditch between them and a third wall to the south, forming a 150-metre arc across the isthmus where the entrance lies. The peninsula measures 180 m north-south by 160 m east-west, with cliffs around the rest of its perimeter. Remains include a rectangular dwelling with rounded corners; a torreón once stood here but has disappeared.

The castro was known locally for decades but only officially documented in the late 20th century. Unauthorized digs in 1968 by amateur archaeologists were followed by test pits between 1970 and 1973, approved by the Real Academia Galega de Belas Artes, which uncovered house walls, pottery fragments, stone slabs and hand mill pieces. Since the last survey of the 20th century the site has remained abandoned.

The Galician writer Ánxela Loureiro set her book Laia, a nena da Illa at this castro, weaving its inhabitants and Roman troops into the story. A local legend, also retold in the book, holds that a farmer from Valón found pieces of castrexo jewellery near the site rather than inside it, as is usual.

The site lies on the Punta del Castro peninsula between Doniños and San Jorge beaches, reached by a vehicle access track installed by the Ferrol port authority; a lighthouse and a ruined army watch post stand on the headland. The perimeter beyond the eastern defences is cliff edge, so keep to the walled arc of about 150 m over the isthmus. The castro has been abandoned since the last survey of the 20th century, with no facilities or marked route.

Archaeological findings on nearby Gabeiras Islands show pottery remains similar to those found at the hillfort itself, suggesting this location was an important center for ancient activities across a wider area. This connection between the fort and the islands reveals how ancient people used a larger territory as an integrated living space.
