Meaning "valley of the groves", this is a small settlement between Blackwood and The Rock. It was the location of one of the coal mines in the area from the early to mid 19th century until it closed in the early 1940s. Some of the houses were built to house mine workers and their families but newer houses have been built there in recent years as the settlement is in an ideal location, being quite secluded and close to the countryside, yet only a few minutes from the amenities of Blackwood.
