Crymlyn Bog Second World War Barrage Balloon Site is a Modern Defence installation located in Wales, designated as a Scheduled Ancient Monument under Cadw reference GM636. The site dates to the Second World War period, when barrage balloons were deployed across Britain as a defensive measure against low-flying enemy aircraft attacks. Barrage balloon sites such as this typically consisted of mooring points, winches, and associated infrastructure positioned to create aerial obstacles and force attacking aircraft to operate at higher altitudes where they were more vulnerable to anti-aircraft fire. The Crymlyn Bog installation represents part of Wales's broader air defence network during the conflict and survives as evidence of civilian and military protective infrastructure from the 1939–1945 period.
