Coed y Caerau Auxiliary Unit Operational Base is a Second World War defensive installation located in Wales, designated as a Scheduled Ancient Monument under the reference MM346. The site dates from the period of heightened invasion threat in 1940–1944, when the Auxiliary Units were established as a clandestine home defence network to conduct guerrilla operations in the event of German invasion. The base comprises physical remains typical of Auxiliary Unit sites, including concealed operational facilities and supporting structures constructed to enable small resistance teams to function independently behind enemy lines. This site represents an important element of Britain's civil defence archaeology and reflects the strategic preparations undertaken during the critical middle years of the Second World War.
