Alexanderstone Mound and Bailey Castle is a motte and bailey fortification located in Breconshire, Wales, dating to the Norman period following the late eleventh century. The site comprises a substantial earthen mound typical of early Norman defensive architecture, accompanied by a bailey or outer enclosure, representing the characteristic two-part castle design employed by Norman settlers in Wales during the post-Conquest period. The monument survives as an important archaeological example of Norman military strategy in the Welsh borderlands, reflecting the pattern of castle construction used to consolidate territorial control in the region. Its earthwork remains retain significant archaeological potential for understanding Norman settlement and the development of medieval fortifications in Breconshire.
