Theddlethorpe St Helen, Pillbox
This standard type 23 pillbox is close to the coast at Theddlethorpe St Helen (TF 483 892).
It was one of many defended observation posts along the Lincolnshire coast and elsewhere in the county.
Construction in concrete between wooden shuttering was quick and economical.
Ken Redmore, 2006
