4th Wall is a free, augmented reality (AR) public art platform exploring resistance and inclusive creative expression.

Excited by augmented reality’s potential to increase access to fine art, new media artist Nancy Baker Cahill founded the 4th Wall app with developer Drive Studios in February 2018. Her intention was to challenge traditional conventions of public art and introduce a participatory, immersive art experience. 

​

The app has since expanded to include geolocated AR land art, curated AR exhibitions, and collaborative projects with artists around the globe. 4th Wall is committed to conceptually rigorous artworks, and intends to prompt thoughtful discourse and activate ideas using the unique affordances of augmentation.
