A cave in the limestone hills flanking the Elwy Valley in North Wales excavated by Stephen Green between 1978 and 1980. Local igneous rock that is rather difficult to work was extensively used by the upper Acheulian communities in the area between about 230 000 and 170 000 years ago to make core tools such as handaxes, points, scrapers, and denticulates, some in the Levallois technique. Hominin remains with Neanderthal features representing at least three individuals were found. They date to about 180 000 years ago and are the earliest finds of this kind in northern Europe.
