Anglesey is a relatively low-lying island with slight risings such as Parys Mountain, Cadair Mynachdy (or Monachdy, i.e., "chair of the monastery"; there is a Nanner, "convent", not far away), Mynydd Bodafon and Holyhead Mountain. It was known as the breadbasket of Wales, referred to during the Middle Ages as Anglesey, Mother of Wales (Welsh: Môn, Mam Cymru). This gave it substantial strategic importance during the struggles between the English kings and the Welsh princes.
Anglesey has many small towns scattered all around the island, making it quite evenly populated. Beaumaris (Welsh: Biwmares), to the south of the island, features Beaumaris Castle, built by Edward I as part of his campaign in North Wales. The town of Newborough (Welsh: Niwbwrch), created when the townfolk of Llanfaes were relocated to make way for the building of Beaumaris Castle, includes the site of Llys Rhosyr, another of the courts of the mediaeval Welsh princes and which features one of the oldest courtrooms in the United Kingdom. Beaumaris acts as a yachting centre for the region with many boats mored in the bay or off Gallows point. Llangefni is located in the centre of the island and is also the island's administrative centre.
