Twm-Barlwm Motte and Bailey Castle is a medieval fortification located in Caerphilly, Wales, comprising a prominent motte standing approximately 65 feet high with a surrounding bailey. The site dates to the Norman period, likely constructed in the twelfth century as part of the broader Norman military expansion into South Wales. The motte's substantial height and steep slopes are characteristic of early Norman defensive architecture, designed to command views across the surrounding landscape and provide a defensible strongpoint for territorial control. The site represents an important example of motte and bailey fortification in the Welsh Valleys region and has been designated as a scheduled ancient monument under Cadw's protection.
