Archaeological excavation was carried out at the former Royal Navy Storage Depot (RNSD) Lower Site, Topsham Road, Exeter by AC archaeology in 2012. Despite considerable truncation of the archaeological deposits due to ploughing and modern construction archaeological features were recorded. Notably a Bronze Age ring ditch, three Later Iron Age roundhouses and some associated postholes were found. Also present across the site were field boundaries of prehistoric to post-medieval date.
