Within Posada's territory was the ancient city of
Feronia or Pheronia, the foundation of which is ascribed to the
Faliscans, which contained a now lost temple to the Etruscan goddess
Feronia. During the
Roman period, the town's importance declined with the foundation of nearby
Portus Luguidonis. In the Middle Ages, Posada was main town of an historical district called
Baronia di Posada or
Baronia Alta (to be distinguished from Baronia Bassa or Baronia di
Orosei/
Galtellì), on the
Tyrrhenian coast of the island. The ancient part of the town is in a spectacular position on the top of a hill, where it preserves a particular
medieval historical center, with ruins of a
castle (
Castello della Fava) and a square panoramic tower of the 13th century. The castle has been the equivalent of a holiday residence for the
Giudichessa Eleanor of Arborea, and was object of alternate possession by the
Giudicato d'Arborea and the
Aragon, during the long fight before the Spanish conquest. The castle became then the seat of the Baron of Posada, a title and a
fief created in 1431 for Don Nicolò Carroz and formally ended in 1856, when it was finally bought by the
kingdom of Sardinia (the last one of all Sardinian fiefs). ==Economy==
