Mold Castle was erected under instructions from the Earl also known by what name?
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.
Earl of Mar The title Mormaer or Earl of Mar has been created several times, all in the Peerage of Scotland. The first and seventh creations are currently extant, and held by different individuals. The first creation of the earldom was originally the provincial ruler of the province of Mar in north-eastern Scotland. First attested in the year 1014, the "seat" or "caput" eventually became Kildrummy Castle, although other sites like Doune of Invernochty were initially just as important.
