Castles and Town Walls of King Edward in Gwynedd
The castles of Beaumaris and Harlech (largely the
work of the greatest military engineer of the time, James of St George)
and the fortified complexes of Caernarfon and Conwy are located in the
former principality of Gwynedd, in north Wales. These extremely
well-preserved monuments are examples of the colonization and defence
works carried out throughout the reign of Edward I (1272–1307) and the
military architecture of the time.
