If this rear façade of the Ca’ d’Zan looks similar to the Ducal Palace in Venice, then you have a good eye for Veneto-Byzantine architecture. John Ringling wanted his winter residence to look like a palazzo along the Grand Canal. The 1,000 foot building is beautifully appointed with Byzantine and Moorish elements and covered with terracotta and glazed titles. The terrace is a marble mosaic in an array of colors. It leads to the waterfront of Sarasota Bay where Mr. Ringling often docked his yacht, the Zalophus.
