an island northwest of Wales

An island off the north coast of Wales. In history, it was known as Ynys Mon, a major Druidic seat of power at the peak of Celtic dominion in Britain.

Anglesey (, pronounced (IPA)), is a predominantly Welsh-speaking island and county at the northwestern extremity of Wales. It is separated from the mainland by a narrow stretch of water known as the Menai Strait. It is connected to the mainland by two bridges, the original Menai Suspension Bridge (carrying the A5), built by Thomas Telford in 1826 as a road link, and the newer, twice reconstructed Britannia Bridge (originally the work of Robert Stephenson), which carries the A55 and the North Wales Coast Railway line.
