Castell Odo

The late Bronze Age hillfort of Castell Odo on the Lleyn peninsula is one of the most important archaeological sites in Wales. It is situated on the summit of Mynydd Ystum and was probably built and colonised by Celtic settlers coming from the Irish Sea in around 400 BC.

Moel Goedog Hillfort

In a commanding position situated on the hills above Harlech are the remains of the suspected late Bronze Age hillfort known as Moel Goedog. It is adjacent to the prehistoric track way of Fonlief Hir, which is indicated by a series of standing stones along the route.

Clogwyn Arllef Hillfort

On the summit of an isolated ridge in the parish of Llanbedr stand the remains of the prehistoric hillfort known as Clogwyn Arllef. The dimensions are roughly 70 metres in diameter from north to south, and 55 metres form west to east. The remains are defined by fallen stone wall which is an average of 2 metres wide.
