On the rio di San Severo (a Venetian canal), in Castello, squeezed between the Codussan Palazzo Zorzi — today the UNESCO seat — and the Palazzo Grimani of Santa Maria Formosa, stands Palazzo Zorzi-Bon: 14th-century architecture retouched in the Renaissance, which still preserves on the piano nobile a pointed-arch five-light window surmounted by a four-light window, with the coloured marbles that made Ruskin cry out at the ’house of bacon’.
