Ca' Rezzonico is a palazzo on the Grand Canal in Venice. Today, it is a public museum dedicated to 18th-century Venice and one of the 11 venues managed by the Fondazione Musei Civici di Venezia. Ca' Rezzonico stands on the right bank of the canal, at the point where it is joined by the Rio di San Barnaba. The site was previously occupied by two houses belonging to the Bon family, one of Venice's patrician families. In 1649 the head of the family, Filippo Bon decided to build a large palazzo on the site.
