Din Lligwy is an ancient fortified village located on the east coast of Anglesey near the village of Moelfre. It dates to the pre-Roman and Roman period but was inhabited by Native Britons. Coins and pottery found here have been dated to the 4th century AD.

This was a farming village that is remarkably preserved for being so old. It is one of our very few examples of how local people lived during the Roman occupation of Britain.

Still visible today are the foundations of both round and rectangular buildings, all built in using locally available limestone. Large amounts of metallic slag as well as remains of several hearths with charcoal formed from oak were found in one of the large rectangular structures, indicating it was a workshop for the smelting and working of iron. The outer protective wall is almost entirely intact, though obviously much shorter than it would have been when the village was occupied.
