Situated a short walk from Venice’s train station and nearby to the famous Restaurants in Venice, Palazzo Labia is a gothic masterpiece now owned by RAI, the Italian state broadcasters. It also happens to be one of the city’s best-kept secrets. Open only three hours a week – telephone reservations obligatory – it is strict enough to throw all but the most keen sightseers off the scent. Step inside, however, and you will see Tiepolo frescoes like you will never see again – surely the finest work that one of Venice’s most favourite sons ever produced.
