Dinas Dinlle Iron Age Hill fort

This coastal Iron Age hill fort in the community of Llandwrog was built on an isolated hill of glacial drift known as Boncan Dinas, but it has now been considerably eroded by the Irish Sea and the feet of tourists. There is a popular award winning beach on the foreshore, providing views of the Northern coast of the Lleyn Peninsula and Llanddwyn Island, Anglesey.
