Porth Mawr

Porth Mawr is shown as a bay on the public map of Pembrokeshire. The saved point is the map point or the centre of its mapped shape.

Porth Mawr is a sea cliff and coastal rock feature located in Pembrokeshire, formed primarily of Carboniferous limestone, approximately 340 to 300 million years old. The cliffs were shaped by marine erosion and tectonic activity, and the area is notable for its dramatic coastal scenery and historical use as a sheltered anchorage.
