Aeolian Hall was a concert hall in midtown Manhattan in New York City, located on the third floor of 29-33 West 42nd Street (also 34 West 43rd Street, from the other side) across the street from Bryant Park. The Aeolian Building was built in 1912 for the Aeolian Company, which manufactured pianos. Located on the site of the former Latting Tower, which during the 19th century was a popular observatory, the 18-story building contained the 1,100-seat Aeolian Hall.
