Righto after taking Mr Bones advice I have decided to post a separate set of pics of an early 19 th century Windpump by the side of the River Ant at Ludham deep in the heart of the Norfolk Broads. Not exactly a difficult place to get to just very muddy underfoot and nearly ended up in the River twice! The Windmill was requisitiond by the local Home Guard and turned into what was a Two Storey Pillbox complete with Embrasures and inner Blastwall albeit a small one!.
Further up the Coast was this weird Pillbox, I have a feeling that the cone on the top may be an Anti Aircraft Mounting
