Ca' Rezzonico site was previously occupied by two houses belonging to the Bon family, one of Venice's patrician families. In 1649 the head of the family, Filippo Bon decided to build a large palazzo on the site. For this purpose he employed Baldassarre Longhena, the greatest proponent of Venetian Baroque. However, neither architect nor client was to see the completion of the Palazzo Bon: Longhena died in 1682, and Filippo Bon suffered a financial collapse.
Giambattista Rezzonico, merchant and banker, bought the palace in 1751 and appointed Giorgio Massari, one of the most highly esteemed and eclectic artists of the day, to complete the works, which proceeded rapidly and in 1756 the building was finished. While the magnificent facade on the Grand Canal and the second floor followed Longhena’s original project, Massari was responsible for the audacious inventions towards the rear of the palace: the sumptuous land-entrance, the ceremonial staircase and the unusual grandiose ballroom obtained by eliminating the second floor in this portion of the building.
As soon as the building was completed, the most important painters in Venice were called upon to decorate it. These were for example Giambattista Crosato, who painted the frescoes in the ballroom and Giambattista Tiepolo, who painted two ceilings in celebration of the marriage between Ludovico Rezzonico and Faustina Savorgnan.
The building was fully complete by 1758, when Giambattista Rezzonico’s younger brother, Carlo, Bishop of Padua, was elected Pope under the name Clement XIII: this was the peak of the family’s fortunes and the palace at San Barnaba celebrated the event in grand style. But by 1810 no family members were left. For the palace and its great heritage of art and history this was the beginning of a long, troubled period of sales and dispersions. After complex ownerships Ca' Rezzonico was sold to the Venice Town Council in 1935.
Ca' Rezzonico opened as a public museum in 1936. Today, it is one of the finest museums in Venice; this is largely because of its unique character, where objects designed for great palazzi are displayed in a palazzo, thus, the contents and the container harmonise in a way not possible in a purpose built museum. Thus, today the palazzo is more sumptuously furnished than ever before.References:
The Château de Chaumont was founded in the 10th century by Odo I, Count of Blois. The purpose was to protect his lands from attacks from his feudal rivals, Fulk Nerra, Count of Anjou. On his behalf the Norman Gelduin received it, improved it and held it as his own. His great-niece Denise de Fougère, having married Sulpice d'Amboise, passed the château into the Amboise family for five centuries.
Pierre d'Amboise unsuccessfully rebelled against King Louis XI and his property was confiscated, and the castle was dismantled on royal order in 1465. It was later rebuilt by Charles I d'Amboise from 1465–1475 and then finished by his son, Charles II d'Amboise de Chaumont from 1498–1510, with help from his uncle, Cardinal Georges d'Amboise; some Renaissance features were to be seen in buildings that retained their overall medieval appearance. The château was acquired by Catherine de Medici in 1550. There she entertained numerous astrologers, among them Nostradamus. When her husband, Henry II, died in 1559 she forced his mistress, Diane de Poitiers, to exchange Château de Chaumont for Château de Chenonceau which Henry had given to de Poitiers. Diane de Poitiers only lived at Chaumont for a short while.
Later Chaumont has changed hands several times. Paul de Beauvilliers bought the château in 1699, modernized some of its interiors and decorated it with sufficient grandeur to house the duc d'Anjou on his way to become king of Spain in 1700. Monsieur Bertin demolished the north wing to open the house towards the river view in the modern fashion.
In 1750, Jacques-Donatien Le Ray purchased the castle as a country home where he established a glassmaking and pottery factory. He was considered the French "Father of the American Revolution" because he loved America. However, in 1789, the new French Revolutionary Government seized Le Ray's assets, including his beloved Château de Chaumont.
The castle has been classified as a Monument historique since 1840 by the French Ministry of Culture. The Château de Chaumont is currently a museum and every year hosts a Garden Festival from April to October where contemporary garden designers display their work in an English-style garden.
