Conwy Castle (Welsh: Castell Conwy, English: Conway Castle) is a medieval fortification in Conwy, on the north coast of Wales. It was built by Edward I, during his conquest of Wales, between 1283 and 1289. Constructed as part of a wider project to create the walled town of Conwy, the combined defences cost around £15,000, a huge sum for the period. Over the next few centuries, the castle played an important part in several wars.
