Storey Arms Anti-invasion Defences is a post-medieval defensive structure located in Breconshire, Wales, comprising infantry support trenches constructed during the Second World War in anticipation of a German invasion of Britain. The site forms part of the wider network of anti-invasion preparations undertaken along the Welsh uplands during 1940 and 1941, when Home Defence Command implemented systematic fortification of strategic locations. The physical remains consist of linear trench systems designed to provide defensive positions and support for infantry operations, characteristic of the emergency fieldworks constructed during the period of heightened invasion threat. The defences represent an important archaeological record of civilian and military mobilisation during Britain's most critical wartime period.
