The following set of images are of a artillery observation post (near Beach Farm, Benacre) with a Suffolk Sq Pillbox nearby. The artillery OP has 15" thick walls and a 12" thick roof; it may have been subjected to gunnery practice (as in the last two pillboxes in my last post) as there is damage to the roof. The Suffolk sq pillbox is again constructed with conventional shuttering as opposed to the pre cast blocks used for shuttering found further south. The concrete weapons shelf is also continuous as opposed to a separate shelf for each embrasure.
