Just as Venice possesses but a single ‘Piazza’ among dozens of campi, it has only one building correctly called a Palazzo. The singularity is important: the Doge’s Palace (Palazzo Ducale), like the Piazza San Marco, was the locus of the Serenissima’s public identity and seat of her republican government. Unlike her rivals in Florence and Milan she had no ruling dynasties to dictate polity, by contrast developing a deep aversion to individual aggrandizement and over-concentrated power. While the person and Palazzo of the Doge embodied their municipal identity, it was in their private houses that Venice’s mercantile oligarchs expressed their own family wealth and status.

These Case (in Venetian parlance Ca’) were built throughout the city. In the absence of primogeniture, many of the two hundred-odd noble families sprung many branches, leading to several edifices of the same name – an obstacle for would-be visitors.

These houses were unlike any other domestic buildings elsewhere in the world: erected over wooden piles driven into the mud flats of the lagoon, they remained remarkably uniform over the centuries in their basic design, combining the functions of mercantile emporium (ground level) and magnificent residence (upper floors).

They were however built in a fantastic variety of styles, Veneto-Byzantine, Gothic, Renaissance, Baroque and Rococo. Sometimes there is a touch of Islamic decoration. As new families bought their way into the aristocracy during the long period of the Republic’s economic and political decline, they had their residences refurbished in Rococo splendour by master artists such as Giambattista Tiepolo. Many of these palaces have survived the virtual extinction of the Venetian aristocracy and retain their original, if faded, glory.

Palaces for nobles will be considered in conjunction with those for the non-noble cittadino (wealthy merchant) class and the housing projects for ordinary Venetian popolani, which rise cheek by jowl in the dense urban fabric.

Some of the places visited are familiar and readily accessible to the public. Others are opened only by special arrangement with the owners, whether a charitable organisation, branch of local government, or descendants of the original occupants. Some of these cannot be confirmed until nearer the time.

A private, after-hours visit to the Basilica San Marco, the mosaic interior illuminated for your benefit, is a special feature of this tour. As is an opportunity to see up close ‘the most beautiful street in the world’, the Grand Canal, from that most Venetian of vantage-points, a gondola.
