Continuing on the North Downs another unusual built pillbox can be found south of Great Copse near Ranmore Common.

This modified type 24 sits at the edge of a very steep forward drop which continues around to its west facing side.

Like the majority of others found along the North Downs Way the defence was built with 51” shell proof front walls, however this is only up to waist level or where the loophole table platform is, above this they are reduced down to 33” to ceiling height.

Three of the four embrasures are the large square concrete castings with the thick metal strips giving additional protection, note the loophole opening is obstructed by 50% restricting the depression of weapon as well as vision!. Inside the west facing loop has a raised platform and an embrasure different from the others as it is no more than a basic narrow slot with minimal vision.

To help clear the inside of the pillbox from fumes and smoke there are three small smoke vents, one frontward and on each rear side walls.

The rear wall is only 24” thick and devoid of loopholes, an unusual and perhaps considered extravagant feature is the brick built platform above the entrance steps.

As with the preceding pillbox at Picket Post the internal space is dissected with a short stubby blast wall.

This is the only shell proof defence on the North Downs Way without provision for the mounting or support of machine gun or the Boys AT rifle, all of loophole apertures are finished in the most basic form. As you can see from the pictures time and the weather has taken its toll on the external brick shuttering.

Defence Structures and sites of all types both above and below ground can be very dangerous. Serious injury or even death can arise from unauthorised entry into such sites and structures. Join a responsible club, group or society who can arrange official visits. The Pillbox Study Group accepts no responsibility for any damages or injuries caused by ignoring this advice. The PSG does not encourage members to undertake the ad hoc clearance of vegetation from pillboxes, as it can expose them to physical damage and inappropriate use, it may also contravene a variety of statutory regulations including, listed buildings and SSSI designations. Vegetation clearance should only ever be undertaken as part of a formal arrangement, having sought and obtained permission from the land owner and other necessary authorities. Damaging a listed or scheduled monument can be considered as a Heritage Crime.
