The Interface area on Northumberland Street in Belfast is a significant urban boundary that reflects the complex social and political history of the city. Located between the Falls Road and Shankill Road, it is marked by a prominent peace wall that physically and symbolically separates two communities. Over the years, efforts have been made to transform this space, with murals, community projects, and security infrastructure coexisting in a shared landscape. The area remains a vivid reminder of Belfast’s divided past, while also serving as a focal point for dialogue, coexistence, and gradual change within the surrounding neighborhoods.
