Legendary style and glamour has returned to Detroit. Following a $200 million renovation, the historic Book Cadillac Hotel has been restored to its original splendor to reclaim  its position as Detroit's premier lodging and social gathering destination. The luxury hotel hotel also features more than 60 residences on the upper floors and some of the Midwest's most dramatic public event spaces. Now included in the National Register of Historic Places, the Italian Renaissance–style hotel, built by Detroit's famous Book brothers, was the tallest building in Detroit and the tallest hotel in the world at its completion in 1924.
