A conservation area for the historic core of Lewes was designated by East Sussex County Council in 1970. It was subsequently extended by the South Downs National Park Authority in 2012. Lewes District Council prepared a Character Appraisal in 2007 whilst the South Downs National Park Authority adopted a Management Plan for it in 2013.
The Malling Deanery Conservation Area, which covers the area surrounding South Malling Church and Malling Deanery was established in 1974 by Lewes District Council. A combined Character Appraisal and Management Plan for it was adopted by the South Downs National Park Authority in 2016.
A plan showing the delineation of both conservation areas, which are contiguous, is below.
The Character Appraisals and Management Plans are documents which contain useful information for those intending to make planning applications in either area and along with the Town of Lewes Neighbourhood Plan are taken into account in their determination by either the South Downs National Park Authority or Lewes District Council as their agents.
The Conservation Areas are hatched, and the yellow areas denote trees.
