Medway is a unitary authority district and conurbation in Kent, South East England. It had a population of 278,016 in 2019. The unitary authority was formed in 1998 when Rochester-upon-Medway amalgamated with the Borough of Gillingham to form Medway Towns. It is now a unitary authority area run by Medway Council, independent of Kent County Council but still part of the ceremonial county of Kent. Medway is one of the boroughs included in the Thames Gateway development scheme. It is also the home of Universities at Medway, a tri-partite collaboration of the University of Greenwich, the University of Kent and Canterbury Christ Church University on a single campus in Chatham, together with the University for the Creative Arts, which had a campus in Rochester but has since closed. Midkent college has taken over the site for it students. Because of its strategic location by the major crossing of the River Medway, the borough has made a wide and significant contribution to Kent, and to England, dating back thousands of years, as evident in the siting of Watling Street by the Romans and by the Norman Rochester Castle, Rochester Cathedral (the second oldest in Britain) and the Chatham naval dockyard and its associated defences. The main towns in the conurbation are (from west to east): Strood, Rochester, Chatham, Gillingham, and Rainham. These are traditionally known as the Medway Towns. Many other towns and villages such as Frindsbury and Brompton lie within the conurbation. Outside the urban area, the villages retain parish councils. Cuxton, Halling and Wouldham are in the Medway Gap region to the south of Rochester and Strood. Hoo St Werburgh, Cliffe, High Halstow, St Mary Hoo, Allhallows, Stoke and Grain are on the Hoo Peninsula to the north. Frindsbury Extra including Upnor borders Strood. The southern part of the urban area is on the north slope of the North Downs, including the suburbs of Walderslade, Luton, Hempstead and Wigmore. Over half of the unitary authority area is rural in nature.
