Defence grouping
Eastern Command: II Corps Line A - The line ran from Beccles in Suffolk to Norwich (where it joined demolition belt FIII), thence via Fakenham to reach the coast at Burnham Market. Not a conventional stop line but one centred around main roads offering no definite obstacle (the River Wensum run more or less between Norwich and Fakenham). All towns forming way points on the line and villages within a mile either side were to be prepared for defence.
RAF Foulsham defences - Ground defences

Event:
Construction, In the period 1940 1941
Field Visit, In 1990/07
Certainly doesn't look in bad condition.. but DOB doesn't record any of the airfield buildings either, I doubt a field visit was ever carried out. There's definitely plenty of opportunity for the Norfolk Chapter to add detail to the DOB database.
