Mold Castle Mold Castle (Welsh: "Castell yr Wyddgrug" ), on Bailey Hill in the town of Mold, Flintshire, Northeast Wales, is a motte-and-bailey castle erected around 1072, probably by the Norman Robert de Montalt under instructions from Hugh d'Avranches, Earl of Chester. Little remains except the mound on which the motte was built. It stands close to the 15th-century parish church, St Mary's Church near the centre of the town.
Arthur, Prince of Wales Arthur Tudor (20 September 1486 – 2 April 1502) was Prince of Wales, Earl of Chester and Duke of Cornwall. As the eldest son and heir apparent of Henry VII of England, Arthur was viewed by contemporaries as the great hope of the newly established House of Tudor. His mother, Elizabeth of York, was the daughter of Edward IV, and his birth cemented the union between the House of Tudor and the House of York.
