Mar-a-Lago National Historic Landmark

Mar-a-Lago () is a resort and National Historic Landmark in Palm Beach, Florida, built from 1924 to 1927 by cereal-company heiress and socialite Marjorie Merriweather Post. The 126-room, 62,500-square-foot house contains the Mar-a-Lago Club, a members-only club with guest rooms, a spa, and other hotel-style amenities. It is located on the Palm Beach barrier island, with the Atlantic Ocean to the east and Florida’s Intracoastal Waterway to the west. At the time of her death in 1973, Post bequeathed the property to the National Park Service, hoping it could be used for state visits or as a Winter White House. However, due to the costs of maintaining the property exceeding the funds provided by Post, and the difficulty in securing the facility in the flight path of Palm Beach Airport, the property was returned to the Post Foundation by an Act of Congress in 1981. In 1985, Mar-a-Lago was purchased by businessman Donald Trump and his then-wife Ivana Trump was put in charge of running the property. Donald Trump retained the property through his two divorces and his family maintains private quarters in a separate, closed-off area of the house and grounds. Since becoming President, Trump has frequently stayed there, referring to it as his "Southern White House". It is the 20th largest mansion in the United States.
