These Vickers Machine Gun pillboxes they are only yards apart, and are situated alongside Plough Lane, Bramshill SU751606.
This is the view an attacker from the west would have had.
This is the view of the rear showing the entrance and a rifle loophole.
They overlook the Whitewater
valley, however there is no evidence of blast walls ever being there, which is what a standard pillbox of this type would have had. Tim Denton who took these photos and supplied the text tells me that they are in superb condition.
This shows the interior of one of the pillboxes showing the table for the Vickers Heavy Machine gun. These pillboxes probably formed part of the GHQ Line (Berkshire/Hampshire/Surrey/Kent) - West - East section of GHQ Line running from Reading through Hampshire and West Surrey to Kent (Leigh), then following in part a line south of the North Downs.
