Castelgenovese
Castelsardo rises above the eastern end of the Gulf of Asinara on Sardinia's northern coast. The town grew around a castle built by the Genoese Doria family, who held it as Castel Doria or Castelgenovese. In 1448 the Aragonese conquered the stronghold and renamed it Castel Aragonese. Its steep site and walls preserved the memory of a long contest for control of the island's northern shore.
