Fawley Hill is the home of Sir William McAlpine and his collection of artefacts from his work over the years. Some years ago, Sir William suggested that an O gauge layout could be built along the balcony, which is some 100 feet long. Hence, Watlington/Wallingford. It has been built by the local O gauge group members, and maintained today largely by Bob Hatfield and his wife.
