Over Time AR, developed by CultureTrust Greater Philadelphia, is an innovative augmented reality app that serves as a public art and technology platform. It offers users the opportunity to delve into the rich history of a city through immersive self-guided tours of public spaces. By leveraging augmented reality technology, users can explore the layers of history, significance, and interpretations of various sites using their personal smart devices. Led by a virtual tour guide, Over Time AR transforms outdoor spaces into interactive art and history museums, enabling users to uncover stories, memories, and diverse perspectives associated with these locations.

The app's inaugural tour, set at the iconic Art Museum steps with poet Ursula Rucker as the host, presents a dynamic experience that combines a living timeline, city sightlines, and a fresh perspective on the famous Rocky statue. Each tour stop prompts users with thought-provoking questions, encouraging them to reflect on the historical significance and personal interpretations of the site. Over Time AR not only provides an engaging and educational experience but also facilitates the collection of visitors' insights and reflections, which are then shared on the Monument Lab website.
