Castell Caer Lleion (Seion)

Castle Caer Lleion, located at the peak of Conwy Mountian (Mynydd-Y-Dref), (at an elevation of 244 metres) to the east of Conwy, is a noteworthy and easily accessible Iron Age hill fort which has spectacular views of the North Wales coast line and the Carneddau Mountains. The hill fort’s original entrance is found on the southern side; the northern side is naturally fortified by the sheer incline of the mountain. There are the remains of numerous stone round houses at the southern end, probably between fifty and sixty of them in total, enclosed within a thick stone wall. Originally the hill fort had a ditch and an earthen rampart, and later an extensive stone wall surrounding the fort, except on the naturally defended northern face. Archaeological excavations at the hillfort in 1951 uncovered some sling stones, querns, and pestle and mortars, but nothing of a datable age. The site can be accessed on foot by various footpaths, and by road via the Sychnant Pass and Mountain Road.
