The town of Castelsardo originates from the castle built in the 12th or 13th century by the Doria family of Genoa. The castle and the village which gradually formed round it where the seat of the Doria's fiefdom in the island called Castel Doria or Castelgenovese, until it was conquered by the Aragonese in the 15th century (1448), and named Castillo Aragonés (Castel Aragonese). Later it became the seat of the bishopric until the Cathedral of Sant’Antonio Abate was built in 1586.

The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
