Castell Aberlleiniog
Castell Aberlleiniog
A Norman motte surrounded by ditch, built c 1088 for Hugh d'Avranche, the powerful first Earl of Chester. The early structuire was replaced in the Civil War with a stone building surrounded by a curtain wall. It is the only motte and bailey castle on Anglesey, and was apparently used by the Home Guard in WW II.
The stone ramparts you can see at the top of the castle mound are part of the Civil War defenses and not the original medieval structure.
