Castle Killibury is in Cornwall, about a mile east of Wadebridge. Excavations have revealed evidence of occupation of Castle Killibury from the Bronze Age through to the Iron Age. Little has been found here from the King Arthur period, except for two shards of Tintagel amphorae pottery. And there is no evidence of refortification of Castle Killibury during that time period. Archeological interpretation is however difficult as the Castle Killibury area has seen extensive ploughed over the centuries, the stratiography of the soil has been destroyed and artifactsmay well have been destroyed too.
Kelliwic is mentioned extensively in early Welsh poetry, and located in Cornwall. The inference is that Welsh writers would have located such an important place in Wales unless folk lore really did point to it as being in Cornwall.
Kilhwch and Olwen mention the fortress five times. In the Welsh Triads, Kelliwic is given as "one of the three. The area between the banks of Castle Killibury national thrones of the Island of Britain, and one of King Arthur's chief seats of empire"
In some legends, Kelliwic plays an integral role in the onset of the Battle of Camlann. "He went to Gelliwig, and dragged Gwenhwyvar from her throne"
It seems that Kelliwic was, in fact, a real place. In 1302 a document records the murder of a man named Thomas of Kellewik near Penzance. Were in fact Castle Killibury and Kelliwic one and the same place?.
