Ruabon (Rhiwabon; r̥ɪʊˈɑːbɔn) is a village and community in Wrexham County Borough, Wales. The name comes from Rhiw Fabon, rhiw being the Welsh word for "slope" or "hillside" and Fabon being a mutation from St Mabon, the original church name, of earlier, Celtic origin. An older English spelling, Rhuabon, can sometimes be seen.
In 2001, more than 80% of the population of 2,400 were born in Wales, with 13.6% having some ability in Welsh.
There is evidence that a settlement existed in Ruabon in the Bronze Age. In 1898, building works in the centre of Ruabon exposed a cist or stone urn containing cremated human remains dating from 2000 years BC. In 1917, the remains of a Bronze Age round barrow were discovered on the playing fields of Ruabon Grammar School; they contained human remains, a flint arrowhead and a bronze axe.
Overlooking Ruabon, the Gardden (Caer Ddin) is an ancient hillfort surrounded by circular ditches, dating back to the Iron Age.
The ancient parish of Ruabon was made up of the townships of Ruabon (which also included the hamlets of Belan, Bodylltyn, Hafod and Rhuddallt), Cristionydd Cynrig (also known as Y Dref Fawr or Cristionydd Kenrick in English), Coed Cristionydd, Cristionydd Fechan (also known as Y Dref Fechan or Dynhinlle Uchaf), Dinhinlle Isaf; Morton Anglicorum (the “English Morton” or Morton Below the Dyke) and Morton Wallichorum (the “Welsh Morton” or Morton Above the Dyke).
In 1844, Coed Cristionydd and part of Cristionydd Cynrig became part of the new parish of Rhosymedre, and Cristionydd Fechan and Moreton Above became part of the new parish of Rhosllannerchrugog.
Later in 1879, Dynhinlle Uchaf and the remainder of Cristionydd Cynrig became the new parish of Penycae.
Ruabon is within the historic county of Denbighshire and, between 1889 and 1974, was administered by Denbighshire County Council. From 1974 until 1996, it was administered as part of Clwyd. From 1996, it has been administered as part of the County Borough of Wrexham.
