This Desk-based Assessment has been prepared for a site at Edgmond Chapel, Church Street in Old Town, Eastbourne in order to establish the likely presence and importance of any archaeological remains and original features of the building that may be affected by the proposed redevelopment of the site into a Supported Living Centre for people with a learning disability. The desk-based assessment has shown that the site is situated in an area of intensive medieval activity focussed on Church Street, with the site having been occupied from then through to the present day. It is very likely that any development will damage or destroy archaeological remains preserved on the site.
