The Robert Treat Center is an office and hotel complex in Newark, New Jersey, named for Robert Treat, who founded the city in 1666. One building originally opened as the Robert Treat Hotel in 1916. The landmark was later converted to an office building after the construction of newer hotel next to it. The adjacent buildings are located at Military Park near the New Jersey Performing Arts Center and New Jersey Historical Society. In 1933, the Hotel was operated by Niagara Falls businessman Frank A. Dudley and the United Hotels Company.
