The Royal Poinciana Hotel was a Gilded Age hotel in Palm Beach, Florida, United States. Developed by Standard Oil founder Henry Flagler and approximately 1,000 workers, the hotel opened on February 11, 1894. As Flagler's first structure in South Florida, the Royal Poinciana Hotel played a significant role in the region's history, transforming the previously desolate area into a winter tourist destination and accelerating the development of Palm Beach and West Palm Beach. Two months later, Flagler's Florida East Coast Railway reached West Palm Beach, while a railroad bridge built across the Lake Worth Lagoon in 1895 allowed guests direct access to the hotel. In 1896, Flagler opened a second hotel nearby, The Breakers. The success of both hotels led to expansions of the Royal Poinciana Hotel in 1899 and 1901. By then, the building had reportedly become both the largest hotel and largest wooden structure in the world at the time.
