Harlech Castle, located in Harlech, Gwynedd, Wales, is a medieval
fortification, constructed atop a spur of rock close to the Irish Sea. It was built
by Edward I during his invasion of Wales between 1282 and 1289. It was part of an
ring of castles eventually stretching from Flint around to Aberystwyth. This was
intended to prevent the region from becoming a focal point of insurrection.
Initially on the coast with the sea lapping at the foot of the Eastern walls, it is
now about a mile inland with sand dunes between it and the shore. Harlech Castle is
perched on a rock, keeping a watchful eye over the spectacular Snowdonian countryside.
