Cayl Castle

In the civil parish of Hayle. In the historic county of Cornwall (Modern Authority of Cornwall, 1974 county of Cornwall).

Leland writes "Cayl Castle, in Phillack parish, is a mile east of Riviere." I've no idea what this is. The given map reference is highly uncertain and based on the parish church of Phillack. It is most probably a reference to a pre-historic earthwork. I've not found any placename like Cayl, but the modern town of Hayle is named after the river Hayle and a transcription error might be possible. The medieval town and manor was called Conerton (and several variants- including Leland's Nikenor, Cenor and Kenor). C19 copper mining and encroachment by sand dunes had serious altered the landscape since Leland's time.
John Smith has done a moderately extensive history of the parish of Phillack and Hayle but does not mention anything like this. See http://freepages.genealogy.rootsweb.ancestry.com/~phillack/index.htm
