Conwy Castle (English: Conway Castle) is a medieval fortification in Conwy, on the north coast ofWales. It was built by Edward I, during his conquest of Wales, between 1283 and 1289.
Following the outbreak of the English Civil War in 1642, the castle was held by forces loyal to Charles I, holding out until 1646 when it surrendered to the Parliamentary armies. In the aftermath the castle was partially slighted by Parliament to prevent it being used in any further revolt, and was finally completely ruined in 1665 when its remaining iron and lead was stripped and sold off.
UNESCO considers Conwy to be one of "the finest examples of late 13th century and early 14th century military architecture in Europe", and it is classed as a World Heritage site. Wikipedia
