Home to one of the largest collections of public art in the country, there’s plenty to see in Philadelphia. Follow one of our self-guided public art tours to uncover an array of sculptures around the city. Tours are grouped by location and highlight whether they are bicycle friendly, walking friendly, or both. Enhance your tour with Museum Without Walls™: AUDIO, our innovative and accessible outdoor sculpture audio program that is available for free by cell phone, mobile app, audio download, or on the web. Museum Without Walls™: AUDIO offers unique histories of sculptures that are not typically expressed on outdoor permanent signage.
