The Marlborough House was built in 1900 by Josiah White III between Ohio Avenue and Park Place on the Boardwalk, in the Queen Anne style. The site now occupied by Bally's was originally the location of two separate hotels: the Marlborough-Blenheim Hotel and the Dennis Hotel. In 1997, The Wild Wild West Casino was opened as an expansion of Bally's. Its historic Dennis Tower was constructed in stages between 19. Bally's is one of the largest hotels on the boardwalk with nearly 1,169 rooms. It is famous for its address of 'Park Place and the Boardwalk', two locations popularized by the board game Monopoly. The Marlborough-Blenheim Hotel stood on the site before the casino was built.
It is owned and operated by Bally's Corporation.
