Overview

History & significance

Twm Barlwm Mound and Bailey Castle is a motte and bailey fortification situated in the Caerphilly district of Wales, designated as a Scheduled Ancient Monument. The site comprises a prominent mound typical of Norman castle construction, dating to the medieval period following the Norman conquest and settlement of South Wales in the late eleventh and twelfth centuries. The castle represents the defensive strategy employed by Norman lords to consolidate territorial control in the region, with its earthwork construction characteristic of early medieval military architecture before the development of stone castles. The monument survives as a significant archaeological record of the Norman colonisation of Wales and the fortification networks established during this formative period of Welsh medieval history.
