Conwy Castle is located in the medieval walled town of Conwy and is open to the public as a visitor attraction throughout the year. The castle is almost unique in the fact that the old town walls remain almost entirely intact and can still be walked on today. The castle was constructed by the English monarch Edward I between 1283 and 1289. The views from the battlements are breath-taking looking out across the Welsh mountains and sea and down the castle’s 125ft Great Hall.
