Format: A5 paperback; 62 pages; maps, photographs, line-drawings and paintings, many in colour South of Lewes High Street runs a filigree of narrow twittens between ancient flint walls - many created in Saxon times, others developed after the Normans arrived. The great castle probably obliterated a similar pattern of footpaths north of the High Street, but many fascinating lanes remain here, too. In this handsomely illustrated book published on behalf of the Friends of Lewes, Kim Clark investigates the history of the twittens, and makes a strong case for their conservation at a time when their character is threatened by careless development.
