During the '20s, while laying out a master plan for Boca Raton, architect and developer Addison Mizner set aside a section of 29 Spanish-style houses in what is now known as Old Floresta. Built primarily for the executives and directors of his company, the houses were painted with pastel colors to deflect the sun. Inside, kitchens were located in the northwest corners so that breezes would provide natural ventilation. Ceilings were nine feet off the ground, which helped keep rooms cool, and many living rooms were fitted with floor-length French doors, once again to take advantage of breezes. The neighborhood is one of the stops during the trolley tours offered every Wednesday by the Boca Raton Historical Society. Other sites on the one-hour tour include the Boca Raton Resort & Club, Town Hall, and the 1930 train depot. Tickets cost $7.50 for the tour, which departs at 9:15 a.m. from Town Hall, 71 N. Federal Hwy., Boca Raton. Call 561-395-6766.
