Llanddew Castle is a medieval castle situated in Wales and protected as a scheduled ancient monument under Cadw reference BR057. The site occupies ground underlain by Pridoli rocks of Silurian age, a bedrock formation comprising mudstone, siltstone and sandstone that has weathered to create the surrounding landscape. This geology would have influenced both the castle's construction methods and the natural drainage of its immediate setting.
The castle represents one of the medieval fortifications built across Wales during the period of Anglo-Norman expansion and subsequent Welsh resistance. Its stone structure would have been quarried from locally available materials, taking advantage of the Pridoli bedrock composition. The site's archaeological significance lies in its role within the military and administrative network of medieval Wales.
Today Llanddew Castle remains an important record of medieval Welsh and Norman settlement patterns. Its protected status recognises the value of the physical remains in understanding medieval defensive architecture and land use in the region. The castle contributes to the broader archaeological heritage of Cadw-protected sites across Wales.
