 This string of homes, built on large parcels of elevated land along the widest point of the bay, is anchored by the John and Mable Ringling Museum of Art at its center.Among them is "Cà d'Zan", the home of Mable and John Ringling, which was restored recently.Many significant structures from the comparatively recent "Sarasota School of Architecture" period of the mid-twentieth century, however, have not survived.
