Gwydir Castle is situated in the Conwy valley, Wales, a mile to the west of the ancient market town of Llanrwst and 1.5mi to the south of the large village of Trefriw. An example of a fortified manor house dating back to c1500, it is located on the edge of the floodplain of the river Conwy, and overlooked from the west by the now-forested slopes of Gwydir Forest.
