Castell Conwy is a late thirteenth-century castle built by Edward I as part of his military campaign to subjugate North Wales following the defeat of Llywelyn ap Gruffydd. Constructed between 1283 and 1287, the castle occupies a prominent rocky outcrop overlooking the town of Conwy and the estuary, with eight towers integrated into its curtain walls and two barbicans controlling access to the inner ward. The fortress was designed as a concentric castle with an inner and outer ward, employing advanced contemporary military architecture to project English royal authority and garrison an English military presence in a strategically important location. The castle has been continuously maintained as a military structure and, since its acquisition by Cadw, stands as one of the finest surviving examples of Edwardian castle architecture in Wales.
