It originally had a motte and bailey structure and the first tower built on top of the motte was made of wood.

During the turbulent times throughout the 12th century, the castle had been handed back and forth between the English and the Welsh.

It was also said to have been significantly strengthened during the 13th and 14th centuries while it was under the administration of the Hastings family.

However, most of the buildings were badly damaged during the English Civil War and the castle was slighted to prevent it from becoming used as a stronghold again.


Barry Castle

Barry Castle belonged to the Barry family.

It was originally a fortified manor which was built during the 13th century.

It was purposely built to replace an earlier structure or earthwork, and was added and strengthened in the early 14th century.

This castle however did not survive the various wars and attacks during the dark ages and all that is left as of today are its ruins.

Deganwy Castle

Deganwy Castle can be found at the mouth of the River Conwy, a river north of Wales.

What is now an amount of ditches and mounds on top of massive rock was formed from the remains of a fortress during the dark ages.

This served as the headquarters of Maelgwn Gwynedd, King of Gwynedd from 520 to 547.

Historians believed it is most likely that Deganwy was the first to occupy the castle during the Roman times.

The castle was rebuilt in stone by the English King Henry III.

However, it was later on abandoned and finally destroyed in 1263 by Llywelyn ap Gruffudd, Prince of Wales.

The ruins seen today are remnants of King Henry’s fortification.
