The Castello di Milazzo is located on the summit of a hill overlooking the town, on a site first fortified in the Neolithic era. The castle was built as a result of the strategic importance of the Milazzo peninsula, which commands the Gulf of Patti, the body of water that separates Sicily from the Aeolian Islands. It also commands one of Sicily's most important natural harbours.
The Greeks modified it into an acropolis, and it was later enlarged into a castrum by the Romans and Byzantines.
In around 843, the Arabs began to build a castle on the ruins of the Greek, Roman and Byzantine fortifications. The castle's keep possibly dates back to this era. The castle was enlarged by the Normans and Swabians. It was extensively modified during the reign of Frederick II of Hohenstaufen.
Between 1496 and 1508, the Aragonese built walls with six semi-circular bastions, encircling the original medieval castle. Between 1525 and 1540, the Spanish built bastioned fortifications around the Aragonese walls and the settlement which surrounded it, expanding the castle into a citadel. The new fortifications were designed by the military engineers Pietro Antonio Tomasello and Antonio Ferramolino. Some outworks were added in the 17th century. Several civil buildings began to be built within the walls of the castle, including the old cathedral and various palaces.
The castle was in Habsburg hands in the first half of the 18th century, before being taken over by the Bourbons. The latter retained the castle until they lost Milazzo to Giuseppe Garibaldi in 1860. The castle was subsequently converted into a prison in 1880, and underwent a number of alterations. The prison closed in 1959 and the castle remained abandoned for a couple of decades.
It is now in good condition, and open to the public.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
