Dover Quad


Dover Quad Pillbox

The Dover Quad pillbox has a square plan and is 4m on a side. It has an overhanging concrete slab roof supported on 8 pillars, one at each corner and in the centre of each wall. This creates 8 wide embrasures offering minimal protection to the occupants but very good observation capability. The roof overhang is intended to provide protection from aerial strafing. It’s postulated that these pillboxes predate the FW3 designs and were built quickly at the start of the war to protect the critical port of Dover. They are generally situated in commanding locations which suggest a dual role as observation posts which would also explain the wide embrasure design. There are 24 examples still extant around Dover.

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.
