 ‘One-Off’ Design Pillbox

Located on the Western side of the Mount

Concrete block constructed ‘one-off’ design. From the front and side elevation it appears that the Pillbox is rectangular but from the rear you can see that it is a ‘wedge’ shape, fitting neatly into the overhang of the natural rock face.

Inside the Pillbox you immediately understand the complexity of the design!

 Type 24 Pillbox

Located on the South-eastern side of the Mount

A Type 24 pillbox with protected rear entrance. This particular Pillbox is used by the National Trust Gardeners as a storage shed!

Located on the South-western side of the Mount


Another Type 24 with a protected rear entrance. Concrete block construction.



All the Pillboxes are located in the ‘Private’ Garden and can only be viewed when they are open to the public. Check with the National Trust before your visit to the Mount to ensure that the gardens are also open along with the castle!

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.
