This paper investigates the use of new media for commemoration of significant events via the creative use of community archive in public spaces. In particular, it focuses on the 75th anniversary commemoration of a traumatic civilian incident in Bethnal Green, London, relating urban infrastructure and the loss and trauma caused to a great number of civilians in 1943. The Bethnal Green Memorial, a physical structure, and two media experiences, a projection and an audio trail, are explored through site observations and related literature. This paper critically reflects on digital experiences for heritage, the importance of anchoring them on the actual sites and creating space for participation.
