Built during the 1920s at a cost of $14 million by Detroit's famed Book brothers, the hotel was designed in the Italian Renaissance style by architect Louis Kamper. When it opened in 1924, the 33-story structure was the tallest building in Detroit and the tallest hotel in the world. A city landmark ever since, generations of Detroiters have celebrated weddings, proms and gala events at the architectural treasure. Presidents Truman, Eisenhower and Kennedy stayed there. So did Frank Sinatra and Babe Ruth.
