Downe, formerly Down, is a village in Greater London, England, located within the London Borough of Bromley but beyond London's contiguous urban area. Downe is 3.4 miles (5.5 km) south west of Orpington and 14.2 miles (22.9 km) south east of Charing Cross. Downe lies on a hill, and much of the centre of the village is unchanged; the former village school now acts as the village hall. The word Downe originates from the Anglo Saxon word dūn, latterly down, hence the South and North Downs. In April 1965, Downe and the remaining part of Orpington Urban District Council, was abolished, and transferred from the historic county of Kent and placed within the newly created London Borough of Bromley.
