Craig Gwrtheyrn (Vortigern's Rock), or Caer Gwrtheyrn (Vortigern's Castle), is associated with the 5th-century British warlord Vortigern.

There is an entrance on the south-west, where two further banks create a barbican and where there is also a small area of chevaux de frise: sharp stones set on end, of which about 30 remain.
