Castro de Liñares

Castro de Liñares is an archaeological site in San Vicenzo, a small coastal locality in Galicia, marking the remains of a fortified settlement built by the so-called castro culture, which flourished across the northwestern Iberian Peninsula during the Iron Age.

Getting there

San Vicenzo sits within the Rías Baixas area of Galicia, a stretch of Atlantic coastline carved by deep inlets. The site is well connected to the surrounding towns of this coastal strip, and like most castros in the region, it occupies raised ground that once gave its inhabitants control over the surrounding land and, in coastal cases like this one, the approach from the sea. A car is the most practical way to reach it, using the local roads linking the peninsula's villages.

What you'll find

The most visible surviving feature of the settlement is the so-called croa — the central, fortified enclosure of the site, ringed by a defensive rampart. At Castro de Liñares the croa is slightly oval in shape, measuring roughly 120 metres along its northeast–southwest axis and about 100 metres along the northwest–southeast axis. That scale marks it as a mid-sized settlement, larger than many modest coastal castros yet still consistent with the kin-based communities typical of the period.

The parapet bordering the croa survives unevenly: in places, particularly along the western side, it still rises clearly above the surrounding terrain, while elsewhere it has been softened by erosion and time until it is barely perceptible. That patchy state is common to many Galician castros that have never undergone full excavation and conservation work, meaning today's visitors read the site mostly through the shape of the land rather than through exposed masonry.

Castros like the one at San Vicenzo were typically built on hills or headlands, commanding views over the surrounding countryside and, for coastal examples, over the ocean itself. Enclosed by ramparts and ditches, they housed farming and herding communities, and their fortifications served both to guard against raids from neighbouring groups and to signal the standing of the lineage occupying the hilltop. Within the defensive perimeter, such settlements usually held clusters of round or oval stone huts, though at Castro de Liñares the details of any surviving internal structures are not widely documented.

Part of a wider heritage

The dozens of castros scattered across the Rías Baixas coastline and further inland across Galicia point to a dense settlement network that existed long before the arrival of the Romans. Even a small, lightly studied site like this one adds a piece to the larger picture of how the early inhabitants of northwestern Iberia related to their landscape, chose defensible ground, and organised themselves into communities of this scale.

Best time to visit

Sites of this kind are easiest to read in the warmer months, when vegetation does not obscure the line of the ramparts and Galicia's weather makes it pleasant to walk across ground exposed to the Atlantic wind. It pairs well with a visit to other stops along the Rías Baixas coast.

Frequently asked questions

What is Castro de Liñares? It is the remains of an Iron Age fortified settlement belonging to Galicia's castro culture, located in San Vicenzo.

What is a "croa"? It is the central, fortified enclosure of the settlement, surrounded by a defensive rampart — here, roughly oval and measuring about 120 by 100 metres.

Has the defensive wall survived intact? No — the parapet's state of preservation is uneven, standing out clearly in places, especially to the west, while barely visible elsewhere.

Why were these settlements built on high ground? Elevated positions gave defensive and visual advantages, which mattered greatly for the security of the farming and herding communities that lived in castros.
