St. George's Channel.

St. George's Channel

A channel is defined as a wide waterway that is situated between two landmasses. St. George’s Channel is a wide water passage positioned between the southeastern part of Ireland in the west and the British territory of Wales in the east. The channel has been named in honor of St. George, England’s patron saint, who had traveled to England by sea from the erstwhile Byzantine Empire. It is believed he approached the British Isles from this channel that now bears his name.

Historically, the name St. George has sometimes been used to refer to the entirety of the water separating Ireland from Wales and England, including the Irish Sea, but in modern times this is less common.
