An interactive sound map of room-tone recordings made inside a selection of WWII ‘pillbox’ defences located around Folkestone town. Created in response to the Sound Diaries 2024 Open Call supported by the Sonic Art Research Unit (SARU), Oxford Brookes University.

These reinforced concrete chambers, commissioned in 1940 to defend against invasion, remain embedded in the landscape, obsolete but perhaps still sentinel. The field recordings explore the variation in their design and acoustic character, while capturing the contemporary acoustic environment from their militaristic vantage point.
