The Breakers, the Chelsea, the Brighton, the Shelburne, the Mayflower, the Traymore, and the Marlborough-Blenheim were demolished in the 1970s and 1980s. Of the many pre-casino resorts that bordered the boardwalk, only the Claridge, the Dennis, the Ritz-Carlton, and the Haddon Hall survive to this day as parts of Bally's Atlantic City, a condo complex, and Resorts Atlantic City.
