Please note, the CITiZAN baseline dataset of sites and features shown on this map comes from a variety of sources:
(RCZAs), selected HERs, the National Trust
and local archaeology groups such as the Thames Discovery Programme. It presents a snapshot in time of a
selective set of site data and shouldn’t be used in lieu of HER records searches for planning purposes.
