Church Island, River Thames Church Island or Church Eyot is an inhabited island in the River Thames in England on the reach above Penton Hook Lock in Staines-upon-Thames, Spelthorne, Surrey. It is in the upper part of the reach. It is approximately 200 m above Staines Bridge, but is thought by some historians to have been the site of the Roman bridges ("Pontes") across the Thames recorded as a waypoint on the Devil's Highway between Londinium (London) and Calleva (Silchester).
