Din Lligwy hut circle is an ancient village site near the east coast of Anglesey, close to the village of Moelfre.
The site is believed to date from the Iron Age and was probably developed and occupied over a long period. For a pre-Roman site, a great deal remains including the enclosing wall and the foundations of many buildings, many of them with substantial and well made foundations constructed from the local limestone. The outer protective wall is almost intact although much reduced in height.
Din Lligwy is situated on a low hill with good views over Anglesey and a reliable source of fresh water nearby. The hill is now overgrown with sycamore and Ash but it is probable that when it was occupied, the village would have had uninterrupted views all around.
