Sannazzaro Castle in Giarole was built by the Sannazzaro family built the castle after receiving special privileges from Frederick I in 1163. It was built between the 12th and 14th centuries. The original structure was modified multiple times in the 18th century. In the 1850s, restoration took place on the north and west wings of the castle which added Neo-Gothic style, which was fashionable at that time.
The grounds of the castle also include a Catholic chapel dedicated to the Blessed Virgin Mary. The Statue of the Virgin of the Rosary, located in the chapel, is part of an annual celebration on the first Sunday of October, that includes a procession around the village, dating back to 1571.
The Counts of Sannazzaro have hosted various monarchs at the Castello Sannazzaro including the Marquesses and Dukes of Montferrat, King Charles Emmanuel IV of Sardinia in 1745, and Emperor Napoleon III and King Victor Emmanuel II in 1859.
Today Sannazzaro castle still remains in the Sannazzaro family and is run as a bed and breakfast.
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.
