Pen Anglas
Pen Anglas is a headland on the coast of Pembrokeshire, which marks the western head of Fishguard Bay, at SM949405: the eastern headland is Dinas Head.
Together with the breakwater which spurs from just south of the headland itself, Pen Anglas protects the ports of Fishguard and Goodwick. It was just west of the head that the French invasion of 1797 landed.
The headland is known for its interesting rock formations. Pen Anglas is formed of a dolerite intrusion and on the northeast-facing cliffs below the stone pillar erected on it, and there are some excellent examples of columnar jointing. Its inclined rockface shows sections through the columns demonstrating the hexagonal cooling joints; on the southwest side of the headland the long axes of the columns can be seen.[1]
Pen Anglas and the coast running from here are within the Pembrokeshire Coast National Park and are the property of the National Trust.
