Clwyd is a region just inside Wales in the north. It contains the Clwydian Range – a ridge rising out of the flat land. The highest point is Moel Famau at 554m.
There are a few stone circles in the area but many are recent. Bronze Age cairns appear on hilltops and in fields. The largest burial mound in Britain is the Gop Cairn near Prestatyn.
The area has long formed the boundary between England and Wales, even before the two countries existed in name. The ridge contains a line of Iron Age hillforts dominating every pass. The Dark Age Offa’s Dyke runs along the ridge and on to the sea. There are plenty of Medieval castles, both earth and stone.
