Nearby is a type 22 shell-proof pillbox. SU 748 543 .
This shows another view of the pillbox.These defences 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) following in part a line south of the North Downs.
Further along the railway is a type 22 shell-proof pillbox. It has an X-shaped blast wall and in 1988 still had its metal embrasure shutters. SU744542.(photos Tim Denton).
