I caught a repeat of an old Time Team programme last night where excavation was taking place on the two objectives in the thread title. I was interested in this as have been researching the Normandy Beach landings and close inland objectives recently but until now had heard nothing about these places. A look on GE indicates no evidence that these objectives ever existed yet with a quick search I found this link where a PDF report can be downloaded on the excavation. Thought I'd post in case anyone is interested in having a read as I think Time Team were limited by the length of the programme. Arromanches Normandy | Wessex Archaeology
