Anti-invasion Defences 2000m NE of Cwmrhwyddfor Farm is a post-medieval or modern anti-tank obstacle situated in rural Wales. The structure was constructed to defend against potential invasion, forming part of the wider network of defensive works built across Britain during periods of military threat. The monument sits upon bedrock composed of Caradoc rocks—mudstone, siltstone and sandstone formations laid down during the Caradocian period—which would have shaped the landscape and influenced its selection as a defensive position.
Anti-tank obstacles such as this were designed to impede the movement of armoured vehicles across open ground. The placement of this example near Cwmrhwyddfor Farm demonstrates how defensive infrastructure was distributed across the Welsh countryside to protect against mechanised assault. The undulating terrain and solid geology of the site provided a practical foundation for construction.
The monument is protected by Cadw, the Welsh Government's historic monuments service, under the reference ME251, recognising its significance as evidence of modern military engineering and civil defence provision. Such obstacles represent an important chapter in Wales's twentieth-century heritage, reflecting the period's strategic concerns and the scale of defensive preparation undertaken across the British landscape.
