This site is dedicated to the study of the Lower Medway Valley in North Kent here defined as that part of the river which cuts through the greensand ridge and the North Downs.  This can be taken to be from East Farleigh to Rochester. The site adopts a multi-discipline approach to the study of the Lower Medway Valley in all its aspects. Diagrams of the river are shown with the source at the top of the page with the river flowing from top to bottom i.e. south to north.  Travelling upstream is moving up the page towards the source and caters for expressions such as 'above the bridge' (source side) or 'below the bridge' (sea side). The orientation of artists impressions and technical drawings are described within the supporting text.
