Naro Castle, locally known as Castello di Naro, lies in the town of the same name, in the Agrigento province on the island of Sicily in Italy.
When Naro Castle exactly was built is unknown. It was first mentioned during the Angevin period (1266-1285). Although tradition has it that it was the residence of the mythical King Kokalos.
During the reign of Frederick III of Sicily, in the first half of the 14th century, the castle was enlarged and the massive square keep was built.
In 1366 the town and castle of Naro were granted to Matteo Chiaramonte by King Frederick III the Simple (or IV if you use the Italian ordinal). During the rest of the 14th century the Chiaramonte family made several changes to the castle.
In 1398 the Chiaramonte family were disowned and Naro Castle and town were declared State property. From then on the castle was used to house a garrison.
Later, when its military importance diminished the castle was turned into a prison.
At present Naro Castle seems to be used. It was closed when I visited and I don't know if it is accessible. A beautiful small castle.
