The site was abandoned suddenly during the 1st century AD, likely due to forced Roman relocation toward the plains.
Archaeologists discovered a unique 'cova da mouras' or drainage system that highlights advanced Iron Age hydraulic engineering.
The defensive wall reaches thicknesses of up to three meters in certain sections to reinforce the hill's natural slope.
Carbon dating of the site's lower strata confirms occupation began as early as the 4th century BC.
The name 'A Cibdá' originates from the local Galician term for 'The City'.
Excavations uncovered a 'pedra do lar' (hearth stone) in almost every excavated dwelling, serving as the center of domestic life.
Castro de Borneiro, also known as A Cibdá, is an Iron Age hillfort situated in the municipality of Cabana de Bergantiños in A Coruña. Occupied from the 4th century BC until the 1st century AD, it represents one of the most significant archaeological sites of the Castro culture in Galicia. The settlement consists of approximately 35 circular and oval stone dwellings, characteristic of pre-Roman architecture in this region. Excavations have revealed a strategic urban layout featuring a defensive wall and a perimeter ditch. The site provides evidence of a sophisticated social organization and a transition into the Romanization period. Artifacts recovered from the site include pottery, metalwork, and grinding stones now held in regional museums. Its elevated location offers a panoramic view of the Anllóns River estuary and surrounding coastal terrain. The site was the first Galician hillfort to undergo systematic archaeological excavation, starting in the 1980s.

There is no shade at the site, so carry sun protection or a hat if visiting during midday.
Do not attempt to touch or move loose stones found within the structures, as these are cataloged archaeological remains.
Stay on the marked paths to avoid damaging fragile archaeological structures; do not sit on or climb the stone walls.
