description of the river cray

The River Cray is a tributary of the River Darent in southern England, rising in Priory Gardens Orpington (London Borough of Bromley), where rainwater permeates the chalk bedrock and forms a pond at the boundary between the chalk and impermeable clay. Initially it flows northwards, past the industrial and residential area of St Mary Cray, through St Paul's Cray (where it once powered a paper mill) and through Foots Cray, where it enters the parkland of Foots Cray Meadows, flowing under Five Arches bridge (built in 1781 as part of the designs for Foots Cray Meadows drawn up by Capability Brown) and past Loring Hall (c.1760), once the home of Lord Castlereagh, who committed suicide there in 1822. It continues northwards through North Cray and Bexley, where there is a restored Gothic cold plunge bath house, built around 1766 as part of Vale Mascal Estate. It is then joined by the River Shuttle and then continues through the parkland of Hall Place, which was built for John Champneys in 1540. The Cray now turns eastward through Crayford and Barnes Cray to join the River Darent in Dartford Creek. The Creek flows northward to enter the River Thames between Crayford Marshes and Dartford Marshes at a point known as Crayford Ness. The villages through which the Cray flows are collectively known as "The Crays".
