The Castellaccio (in dialect Cast’ddazz’) is built on the highest point of the village of Aidone, in Sicily. In a strategic position, with a panoramic view at 360°, it allowed to control the main communication routes in central Sicily. The construction dates back to the XI century, to the Norman period, but it was perhaps preceded by a Saracen fortress. The castle was a main bulwark for the barons lords of Aidone, so much so that it was impregnable and could be accessed only by the ancient street located at noon. When this manor house was attacked by the troops of Robert of Anjou with the betrayal of the captain Bullock degli Uberti was possible conquering it and even the King Frederick III had to use of the machines of war to put the siege to the Angevin troops.
This castle was further fortified by Count Enrico Rosso senior in 1351 that had the need of a department of knights able to attack on the plain of Catania the enemy Artale Alagona. Was the center of the feud of Aidone and it was here that the feudal entertained in 1396 the real Mary and Martin I of Sicily and in May 1411, Bianca of Navarra dictated some letters with the help of Protonotaro the Kingdom Bartolomeo Gioeni, Baron of Aidone and son Perrone to its loyal to counteract the enemy of the crown: the great admiral Bernardo Cabrera.
Fell into ruin as a result of the earthquake of 1693 and subsequently was abandoned. It was probably part of a network of fires of sighting with the castles of Enna, Agira, Pietratagliata and others.
