Edgware (/ˈɛdʒwɛər/) is a district of North London, in the London Borough of Barnet. Edgware is centred 10 miles (16 km) north-northwest of Charing Cross and has its own commercial centre. Edgware has a generally suburban character, typical of the rural-urban fringe. It was an ancient parish in the county of Middlesex. The community benefits from some elevated woodland on a high ridge marking the Hertfordshire border of gravel and sand. Edgware is identified in the London Plan as one of the capital's 35 major centres. In 2011, Edgware had a population of 76,056. Edgware is principally a shopping and residential area and one of the northern termini of the Northern line. It has a bus garage, a shopping centre called the Broadwalk, a library, a hospital—Edgware Community Hospital, and two streams—Edgware Brook and Deans Brook, both tributaries of a small brook known as Silk Stream, which in turn merges with the River Brent at Brent Reservoir.
