Aberffraw is a small village and community on the south west coast of the Isle of Anglesey , in Wales, by the west bank of the Afon Ffraw. Access by road is by way of the A4080 and the nearest rail station is Bodorgan. In the early Middle Ages Aberffraw was the capital of the Kingdom of Gwynedd from c.860 AD until c.1170. Under the eponymous Aberffraw Dynasty it came to be the most important political centre in medieval Wales. The Llys remained the symbolic throne of the Kings of Gwynedd from the 9th century to the 13th century. The Royal Annals of Edward I of England show the Llys was dismantled in 1315 to provide building materials for nearby Beaumaris Castle.
