Plas-yn-Rhiw

Plas-yn-Rhiw is a 16th Century manor house which overlooks Hell’s Mouth (Porth-y-Neigwl) on the Lleyn Peninsula. There has apparently been habitation at the site for over a thousand years, for there was a fortified house on the site in around 900AD built by Meirion Goch (a noble man of the minor gentry) to prevent incursions by Vikings into Porth-y-Neigwl.
