Definition of St george's channel

St George's Channel (Welsh: Sianel San Siôr, Irish Muir Bhreatan) is a channel connecting the Irish Sea to the north and the Atlantic Ocean to the southwest. Historically, the name encompassed all the waters between Ireland in the west, and Wales and the West Country in the east; thus the Bristol Channel opened into Saint George's Channel. The name is now usually applied only to the waters near the narrowest part of the channel, between Carnsore Point in Wexford and Saint David's Head in Pembrokeshire. The sea to the north is now simply considered the South Irish Sea; the sea to the south is considered part of the Celtic Sea. However, it remains common in Ireland to talk about a cross-channel trip, cross-channel soccer, etc., where "cross-channel" means "to/from Great Britain".
