Beaumaris (Welsh: Biwmares) is a former royal borough, a community, and the former county town of Anglesey, Wales. It was located in the commote of Dindaethwy and historic rural deanery of Tindaethwy, and is at the eastern entrance to the Menai Strait, the tidal waterway separating Anglesey from the coast of North Wales. At the 2001 census it had a population of 2,040.
Beaumaris was originally a Viking settlement known as Porth y Wygyr («Port of the Vikings»), but the town itself began its development in 1295 when Edward I of England, having conquered Wales, commissioned the building of Beaumaris Castle as part of a chain of fortifications around the North Wales coast (others include Conwy, Caernarfon and Harlech).
The castle was built on a marsh and that is where it found its name: the French builders called it beaux marais which translates as «beautiful marshes».
The ancient village of Llanfaes, a mile to the north of Beaumaris, had been occupied by the Anglo Saxons in 818 but had been regained by Merfyn Frych, King of Gwynedd, and remained a vital strategic settlement. To counter further Welsh uprisings, and to ensure control of the Menai Strait, Edward I chose the flat coastal plain as the place to build Beaumaris Castle. The castle was designed by the Savoyard mason Master James of St. George and is considered the most perfect example of a concentric castle. The ‘troublesome’ residents of Llanfaes were removed en bloc to Rhosyr in the west of Anglesey, a new settlement King Edward entitled «Newborough». French and English masons were brought in to construct the castle itself and the walled town.
Beaumaris was awarded a Royal Charter by Edward I, which was drawn up on similar terms to the charters of his other castle towns in North Wales and intended to invest only the English and Norman-French residents with civic rights. Native Welsh residents of Beaumaris were largely disqualified from holding any civic office, carrying any weapon, and holding assemblies; and were not allowed to purchase houses or land within the Borough. The Charter also specifically prohibited Jews (who had been largely expelled from most English towns) from living in Beaumaris. A requirement that all trade in the immediate area be conducted at Beaumaris meant the town became the main commercial centre of Anglesey.
Beaumaris became one of the three most important Saxon ports in Britain; and was also the port of registration for all vessels in North West Wales, covering not only every harbour on Anglesey but also all the ports from Conwy to Pwllheli. Shipbuilding was a major industry in Beaumaris. This was centred on Gallows Point — a nearby spit of land extending into the Menai Strait about a mile west of the town. Gallows Point had originally been called «Osmund’s Eyre» but was renamed when the town gallows were erected there — along with a «Dead House» for the corpses of criminals dispatched in public executions. Later, hangings were carried out at the town gaol and the bodies buried in a lime-pit within the curtilage of the gaol. One of the last prisoners to hang at Beaumaris issued a curse before he died — decreeing that if he was innocent the four faces of the church clock would never show the same time.
