The Ca' d'Oro, or Palazzo Santa Sofia, is a palace on the Grand Canal in Venice, northern Italy. Ca' d'Oro or Cadoro translates to "House of Gold" or "Golden House" in English because of the gilt and polychrome external decorations that once adorned its walls. It was designed by Marino Contarini and later restored by Baron Giorgio Franchetti. This message was also conveyed as the palace was built not far from the Rialto Bridge on the left bank of Grand Canal of Venice, which was and remains the main thoroughfare in Venice.
The facade is divided into three distinct stories: a lower loggia (covered corridor), a middle balcony, and an upper balcony.
Long rows of arches and windows face the canal that provide an abundance of natural lighting in the interior.
