Caer Drewyn

Caer Drewyn is an early Iron Age hillfort to the north of the town of Corwen, Denbighshire [1]. Caer Drewyn is the most southerly hillfort in the Clwydian Range and Dee Valley Area of Outstanding Natural Beauty [1]. It is situated on the spur of a hill between Llangollen and Corwen, commanding the valley junction and fertile plain at the confluence of the River Dee and the River Alwen [1]. The earliest structure was a small enclosure built against a natural rock outcrop [1]. A later, larger fortress was surrounded by a dry-stone wall, probably derived from the abundant scree in the area, and does not have the earthen ramparts of other local hillforts [1]. Caer Drewyn is an Iron Age fort dating back to about 500 BC, however it was in use as a defensive position long after this [1].
