Old Street Roundabout

Old Street Roundabout is a roundabout located on the boundary of the London Borough of Hackney and the London Borough of Islington. It is an interchange system at the junction of Old Street and City Road. It is sometimes known as St. Agnes Well after the shopping centre beneath it, while the area surrounding the roundabout is often colloquially known as Silicon Roundabout, owing to the prominence of British web-based companies there.
