The earliest inhabitants of the vale of Elwy lived at the nearby Paleolithic site of Pontnewydd (Bontnewydd), which was excavated from 1978 by a team from the University of Wales, led by Stephen Aldhouse Green. Teeth and part of a jawbone excavated in 1981 were dated to 225,000 years ago. This site is the most north-western site in Eurasia for remains of early hominids and is considered of international importance. Based on the morphology and age of the teeth, particularly the evidence of taurodontism, the teeth are believed to belong to a group of Neanderthals who hunted game in the vale of Elwy in an interglacial period.
