Art UK has catalogued more than 6,600 street art murals and wall-based artworks from across the United Kingdom, spanning everything from ancient church wall paintings to contemporary spray-painted pieces by artists like Banksy, Rogue-one, and The London Mural Company. Volunteers dedicated over 5,000 hours to locating and photographing the works, creating a living digital archive that preserves ephemeral public art against the threats of weather and redevelopment.
