In depth
The fuller history
Castell Aberlleiniog is built in a strategic position beside the Menai Strait opposite the Norman castle at Abergwyngregyn, showing that visual communication was important to the Norman invaders. It was probably erected by Hugh d'Avranches, 1st Earl of Chester, when he conquered Gwynedd in 1088. There are few historical documents that detail the events the castle has seen through its life, however some do survive, including a record of a siege in 1094 by Gruffudd ap Cynan on his return from Ireland. The siege was successful, 124 Norman defenders died in the battle.
