we go back to the 18th century, during the reign of the bourbons in spain. the construction of the fortress began in 1740, simultaneously with the cast elo do cardeal (cardinal′s cast le), located on the opposite shore of the corcubión estuary. it was named cast illo del príncipe in honor of the son of carlos iii of spain, the future king carlos iv.
by the end of the 19th century, the cast le ceased to be state property after a public auction. it had several owners, with galician businessman xosé ramón oreiro making significant renovations in 1985, turning it into a luxury residence.
like the cardenal cast le, it was equipped with 12 artillery pieces in various towers facing the sea. a large central building directed its wings towards the half-bastions of the ravelin, including quarters for the garrison, which housed 88 soldiers, warehouses, and a powder magazine. the finely carved stonework of the exterior and much of the interior constructions magnificently stand out both from the sea and from the land, where it had a moat and a bridge leading to the center of the fortress.
currently classified as a cultural heritage site since 1994, forming part of the cultural heritage of galicia.
