Flagler Museum

Henry Flagler, one of the founders of Standard Oil, built Whitehall for his third wife, Mary Lily Kenan.

The site of the home was purchased for $50,000 in 1893 (equivalent to $1,792,000 in 2025) by Flagler. The site was later surveyed for construction in July 1900 and the home was completed in time for Flagler and his wife to move in on February 6, 1902. The architects were John Carrère and Thomas Hastings, who had earlier designed the Ponce de Leon Hotel and several other buildings in St. Augustine for Flagler. Whitehall was to be a winter residence, and Henry gave it to Mary Lily as a wedding present. They would travel to Palm Beach each year in one of their own private railcars, one of which was No. 91.

Flagler died of injuries sustained in falling down a flight of marble stairs at Whitehall in 1913, at the age of 83. Mary Lily died four years later, and the home was devised to her niece Louise Clisby Wise Lewis, who sold the property to investors. They constructed a 300-room, ten-story addition to the west side of the building, obliterating Mr. Flagler's offices and the housekeeper's apartment, and altering the original kitchen and pantry area. Carrere and Hastings were the architects of the 1925 reconstruction. In 1939 it was described as a $4,000,000 building and Palm Beach's second-largest hotel.

Museum

In 1959, the site was saved from demolition by one of Henry Flagler's granddaughters Jean Flagler Matthews. She established the Henry Morrison Flagler Museum non-profit corporation, which purchased the building in 1959, opening it as a museum in 1960. The upper ten stories of the hotel addition were demolished in 1963 in preparing the museum for the public.

Today, Whitehall is a National Historic Landmark and is open to the public as the Henry Morrison Flagler Museum, featuring guided tours, exhibits, and special programs. The museum offers several programs, many of which are seasonal, lasting only from October to January. In addition to an annual chamber music series, the Flagler hosts the Whitehall lecture series, which brings "experts and best-selling authors to discuss Gilded Age topics, events, and local history." Past lecture series include historical talks about the dawn of the Progressive Era, World War I, Gilded Age presidents, engineering feats, and Metaphysical America: Spirituality and Health Movements During the Gilded Age. The Flagler also holds a special exhibition each year, often showcasing Gilded Age paintings, sculptures, glamour photography, or material culture, such as board games, jewelry, cartoons, Tiffany & Co. silver pieces (including ones displayed at the 1893 Chicago World's Columbian Exposition), and women's fashion. It also hosts a variety of local galas and balls throughout the year. The Museum is located at Cocoanut Row and Whitehall Way in Palm Beach.
