Paris-based Montparnasse 56 Group (M56) announced in 2014 that it would open an observation deck on the 57th floor of One Liberty Place.

[2] The One Liberty Observation Deck, also called Philly from the Top, opened to the public on November 28, 2015.

[4][5] On September 15, 2020, the One Liberty Observation Deck suspended operations indefinitely due to a decline in visitors caused by the COVID-19 pandemic.

After purchasing a ticket, visitors could choose to stand in front of a green screen to have a photograph taken.

Visitors then boarded an elevator, where a video with surround sound was presented about the observation deck and the city.
