In the title of America's most affluent community were up for grabs, Palm Beach would be a formidable competitor for the crown. The city's ultraexclusive tone is set by the ornate architecture of its stunning mansions and public buildings. Developer Addison Mizner, who began building here in the 1920's, created the Moorish-Gothic style that is visible in virtually all of this world-famous enclave's landmarks. Mizner's touch turned Palm Beach into a kind of architectural new-Camelot, the perfect backdrop for the winter addresses of Kennedy's, Rockefellers, and Vanderbilts. But Palm Beach proper is just a small section of the Palm Beach County coast. From Jupiter at the northern end to Boca Raton in the south, a long and pristine stretch of shoreline is dotted with luxurious communities where world-class shopping and recreation are enjoyed year-round.
