As the history of these Venetian houses are long and convoluted (they have been rebuilt and restyled extensively over time), rarely do original furnishings exist. While Ca'Rezzonico retains many of its original frescos, a large collection of period paintings and furnishings have been added and are displayed in situ. Included are rooms moved from other houses, the interior of a Venetian pharmacy, and a gallery of some very lovely paintings. Perhaps my favorite rooms are those moved from the Villa di Zianigo, which feature Giandomenico Tiepolo's playful frescoes of 18th-century life and follies.
Unfortunately, photographs were not allowed inside (though I did sneak a few !!), but you can see more here.
