Rhos (North Wales)
is a region to the east of the River Conwy in North Wales. It started as a minor kingdom then became a medieval cantref, and was usually part of the Kingdom of Gwynedd.
Kingdom: history and archaeology
Rhos is identified as a small kingdom during the sub-Roman and early medieval periods in an Old Welsh genealogical document "Ancestry of the Kings and Princes of Wales" listing thirteen of its kings.The most famous monarch was perhaps Cuneglasus, who lived in the early 6th century and was denounced by the monk, Gildas. He wrote that Cuneglasus was the "guider of the chariot which is the receptacle of the bear". The latter may refer to a "Fort of the Bear", possibly Dinerth, the name of a hillfort on Bryn Euryn in Llandrillo yn Rhos. The road that runs below the western side of the hill is still called Dinerth Road and Dinerth Hall is nearby.
The Gwynedd Archaeological Trust has undertaken a trial excavation of this hillfort and set up related information boards in Colwyn Bay Library. Their investigations revealed a massive defensive stone wall, well built and faced with good-quality limestone blocks originally rising to about ten feet high. The ramparts were eleven and a half feet thick. These defences are unlike those of Iron Age hillforts but comparable with similar Medieval fortifications, so may represent a possible stronghold of the Kings of Rhos.
