Conwy is one of Europe's finest examples of a mediæval walled town. The magnificent Conwy Castle was built by Edward I between 1283 to 1289 and, together with the castles and walls of Harlech, Caernarfon and Beaumaris, is a World Heritage Site. Conwy was the original site of Aberconwy Abbey, founded by Llywelyn the Great, which was moved up the valley to Maenan by Edward I when the castle was built. The parish church still retains some parts of the old abbey church.
