Crymlyn Bog Second World War Barrage Balloon Site is a Modern Defence installation located in Wales, designated as Scheduled Ancient Monument GM636. The site dates from the Second World War period when barrage balloons were deployed as aerial defence measures against low-flying enemy aircraft. Crymlyn Bog's location in the industrial landscape of South Wales made it a strategically important position for such defensive infrastructure, protecting nearby towns and industrial facilities from air attack. The physical remains at the site reflect the temporary yet purposeful nature of wartime defences, documenting a significant aspect of Wales's home front experience during 1939–1945.
