Anglesey is a low-lying island off the North Wales coast, with just a few significant elevations, such as Holyhead Mountain (the highest point at 220m), and the weird lunar-like landscape of Parys Mountain. The island is separated from mainland Wales by the Menai Strait, a mere 250m wide at its narrowest point, spanned by two great bridges: the Menai Suspension Bridge designed by Thomas Telford in 1826, and the Britannia Bridge.

Formerly part of Gwynedd, Anglesey is itself a group of islands including Holy Island and other smaller islands that now comprise the Isle of Anglesey County. The island is a stronghold of the Welsh language, with almost 75% of the island's inhabitants being Welsh speakers. Its Welsh name is Ynys Môn.

The island has a considerable prehistory with megalith monuments and menhirs dotted widely about the landscape, and these great monuments will feature in future stamp issues. Birds, too, will feature in forthcoming issues: the island has recorded no fewer than 323 bird species over the years including one now extinct species, the Great Auk, along with 2 globally threatened species and numerous rare/accidental species.
