Bletchingley Castle is a ruined castle and set of earthworks partly occupied by three buildings. The Scheduled Ancient Monument is directly beside the Greensand Way below it to the south in the village of Bletchingley in Surrey. The site's tower standing from c.1170 to 1264 had a panorama from one of the narrower parts of the Greensand Ridge, which runs from mid-Kent to south-west Surrey.
