Moel Arthur

Moel Arthur ("Arthur's Hill") is an Iron Age hillfort in Flintshire, Wales, at the boundary with Denbighshire, about 5 mi east of Denbigh.

It is on a prominent hill, height 455.8 m, in the Clwydian Range; it overlooks the Vale of Clwyd to the west. Offa's Dyke Path skirts the hill. It is about 1 mi south-east of the hillfort of Penycloddiau.

Description
The oval fort is about 160 m north–south and 140 m east–west, enclosing an area of 1.8 ha. There are two large banks and ditches to the north, where the hill slope is not steep; above the steep south-west, south and east slopes there is a single bank. At the north-east, at the edge of the steeper slopes, there is a narrow inturned entrance with an oblique approach. The form of entrance, and the simple plan of the fort, suggest that it is an early example.

Within the fortifications, there is a rounded summit. In the north and east of the interior there is a broad terrace, and building platforms have been found.

There was excavation in 1849 by Wynne Ffoulkes. He found "coarse red Roman pottery" which has not been preserved; it is not known if it was Roman, which would suggest occupation into the Roman period, or prehistoric. He found traces of a drystone construction, destroyed during the excavation, near the south of the entrance. In 1962, three copper Bronze Age axes were found within the defences.
