Their origin is uncertain, however, a number of place names are similar to what were Celtic regions in what is now the Bordeaux region of France as Llanmadoc and Landes du Médoc, Gwynedd and Gironde, Demetae and Devèze, suggestive of Pre-Roman Celtic Northerly travels on the portside of the North Atlantic Current.
The hill’s position above the village of Llanmadoc within 2 km of Gower’s northwest coast enables wide panoramas to be enjoyed over the western end of the peninsula and the surrounding Loughor estuary, Rhossili Bay and Carmarthen Bay.
There exists an alternative explanation, namely that the name comes from a small Welsh village, Llanmadoc on the Gower Peninsula of Wales, not far from the city of Swansea, which is in turn named for a place called Médoc in Bordeaux, France.
