Even on a tight schedule, Ca' Rezzonico earns the hours.
Allow 1–1.5 hr.
This Baldassare Longhena palazzo lets you actually walk through a fully furnished 1700s Venetian noble house — ballroom with trompe-l'oeil ceilings, Tiepolo frescoes, period rooms — answering 'what was it like to live in one of these palaces?'. The catch: it's a niche pleasure for lovers of Settecento decorative arts, and casual visitors may find the period furniture less thrilling than the Grand Canal facade promised.
