The peninsula of San Raineri, on which Forte del Santissimo Salvatore was eventually built, had been inhabited since antiquity, and Greek pottery dating back to the 8th century BC was found at the site. The fort got its name from a monastery and church dedicated to the Holy Saviour, which were built on the peninsula in the Middle Ages. In around 1081, a tower dedicated to Saint Anne was built on the peninsula, and it saw action during the War of the Sicilian Vespers in 1282.
In the 1540s, the fortifications of Messina were being modernized due to fears of the expanding Ottoman Empire. The monastery and other medieval buildings were demolished to make way for Forte del Santissimo Salvatore, but the church and tower were retained and incorporated into the new fort. The fort was completed in 1546 to a design by Antonio Ferramolino, a military engineer from Bergamo. In 1549, the fort's gunpowder magazine blew up, destroying the church in the process.
The fort was captured by local rebels during the 1674 uprising against Spanish rule. After the revolt was suppressed in 1678, the Real Cittadella was built in the centre of the San Ranieri peninsula, close to Forte del Santissimo Salvatore. The fort was damaged during the earthquake of 1783, but was repaired soon afterwards.
During the Sicilian revolution of 1848, the fort and the nearby Cittadella remained in Bourbon hands, and was used to bombarded the city of Messina, which had been captured by rebels. It was eventually captured by Piedmontese forces during the Expedition of the Thousand in 1861.
The fort was again severely damaged in the earthquake of 1908. The walls facing the port of Messina had to be demolished a year later. In 1934, a large statue of Saint Mary, known as the Madonna della Lettera was erected in the fort, on the site of the medieval tower of St. Anne. Some restoration work has been carried out at the fort. It is still military property, being located near the Italian Coast Guard's base in Messina.
The fort has a polygonal shape running along the natural shape of the peninsula. The extremity is occupied by a semi-circular bastion known as Forte Campana. The medieval tower of St. Anne was incorporated into the bastion, and its remains can still be seen.
The fort's land front originally consisted of two bastions linked together by a curtain wall containing the main gate. One of the bastions is still intact, but the other one was demolished after it sustained damage in the earthquake of 1908.
The land front was linked to the semi-circular bastion by two curtain walls, each containing artillery batteries and a small bastion. The wall facing the Strait of Messina is still intact, but the one facing the harbour was demolished after the earthquake.
References:The Château de Chantilly comprises two attached buildings: the Petit Château built around 1560 for Anne de Montmorency, and the Grand Château, which was destroyed during the French Revolution and rebuilt in the 1870s. Owned by the Institut de France, the château houses the Musée Condé. It is one of the finest art galleries in France and is open to the public.
The estate"s connection with the Montmorency family began in 1484. The first mansion (now replaced by the Grand Château) was built in 1528–1531 for the Constable Anne de Montmorency by Pierre Chambiges. The Petit Château was also built for him, around 1560, probably by Jean Bullant. In 1632, after the death of Henri II, it passed to the Grand Condé who inherited it through his mother, Charlotte Marguerite de Montmorency.
Several interesting pieces of history are associated with the château during the 17th century.
