One Liberty Observation Deck
Climb up Philadelphia's tallest enclosed observation deck to get an amazing view of the city!
Located on the 57th floor of One Liberty Place, 883 feet above Center City, One Liberty Observation Deck provides spectacular 360-degree views of the city and its suburbs. Montparnasse 56 (or M56), the company that manages the observation decks in Chicago's John Hancock Tower and Paris' Montparnasse 56 Tower, brings the first highly accessible viewing area of its kind to Philadelphia.
In addition to panoramic views, One Liberty Observation Deck includes interactive experiences and installations, including a larger-than-life Benjamin Franklin. Interactive, multilingual touch screens mirror the view outside and allow visitors to point and zoom in on a single point hundreds of feet below.
