St. Mark's Basilica, Venice, Italy

St Mark’s Basilica (Italian: Basilica di San Marco in Venezia) is the most famous of the churches of Venice and one of the best known examples of Byzantine architecture. It lies on St Mark’s Square, adjacent and connected to the Doge’s Palace and has been the seat of the Patriarch of Venice, archbishop of the Roman Catholic Archdiocese of Venice since 1807. For its opulent design, gilded Byzantine mosaics, and its status as a symbol of Venetian wealth and power from the 11th century on, the building was known by the nickname Chiesa d’Oro (“church of gold”).(wikipedia)
