Relief map

Historically, the entire marine area between Ireland and south-west Great Britain from the Lleyn Peninsula to Land's End or Cape Cornwall was called St. George's Canal. The name is derived from a 14th century legend according to which St. George crossed the canal on his journey from Byzantium to Britain.
