Trereen Dinas
Gurnard's Head is the site of an Iron Age promontory fort known as Trereen Dinas, the meaning of which is along the lines of "fort at the farm on the point". The narrowest part of the promontory was fortified to create a defended enclosure, protected on 3 sides by the cliffs. The remnants of the fortifications are still visible as a ditch and a bank with some drystone walling.
The circular foundations of a group of around 15 Iron Age huts have been found on the grassy east side of Gurnard's Head, with another smaller group of around 3 huts towards the neck of the headland. There were also finds of Iron Age pottery and a cache of rounded beach pebbles likely to have been used as slingshot.
