Exchange Square in Manchester city centre was built after an IRA bombing in 1996 destroyed parts of the area. The landscape architect Martha Schwartz was commissioned to design Exchange Square. The design aims to create a public space that can accommodate events, improve pedestrian movement, and respect the historic buildings around it while addressing level changes in the area. The design uses ramps, levels, lighting, and other elements to achieve these goals and connect historic and modern parts of the city centre. The design has evolved over time with additions like a large screen, and future connections like a new Metrolink stop may further change the space.
