Old Street Roundabout is a roundabout located on the boundary of the London Borough of Hackney and the St Luke's area of the London Borough of Islington, in central London. 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 technology companies there. In 2019, major refurbishment work started to renovate the entire area to create a more pedestrian and cycle friendly environment, which will open in 2020.
The shopping complex in the underpass at the centre of the roundabout is named St. Agnes Well, after an ancient well thought to have been located about to the east, at the junction of Old Street and Great Eastern Street. Remnants of the well can be found within Old Street station.
The term Silicon Roundabout refers to the high number of web businesses located near the Old Street Roundabout, by analogy to Silicon Valley in California.
