Castell Carn Fadrun and Iron Age Hill Fort

This is a twelfth century Welsh stone castle and is set within the remains of a large Iron Age hillfort. The hill fort is made up of two enclosures, with the larger surrounding the smaller. There are foundation remains of round and rectangular buildings in and outside of the enclosure from the Iron Age. The later castle is made up of the remains of a dry stone wall enclosure and is at the highest point of the hill. The site is located on the Llŷn Peninsula, off the B4415 about five miles west of Pwyllheli.
