8 Magnificent Castles in Ireland

We have compiled a list of 8 Castles that are on our must see list of Medieval Castles!

Until the 12th century, castles in Ireland were not a common sight.

The Anglo-Saxon nobility still ruled in Ireland, despite the Norman Conquest in the neighboring England, and the nobles of this aristocracy generally built fortifications quite different from Norman castles.

By the last quarter of the 12th century, the Normans had launched large-scale expansion of their dominion into Ireland.

To fully subdue the Irish nobility and cement Norman control over Ireland, the Norman barons and lords built frequent castles all over Ireland.

It was during this early period of Norman Conquest that most of the iconic castles in Ireland were built.


Following is the list of some of the most notable Irish castles

Cloughoughter Castle

The original construction of the Cloughoughter Castle began after the Norman Conquest of Ireland.

The structure was started in the 13th century under Norman control, but before it could be completed, the control of the castle fell to the O’Reilly clan.

The clan then had the castle completed and it remained in its possession for several subsequent centuries.

During the Cromwellian era, the castle sided with the royalist cause.

As a result, it was heavily bombarded by the Cromwellian troops and finally succumbed to the attack.

Due to this bombardment, the medieval structure of the castle underwent significant damage. It has been restored since and is well-preserved today, being a popular tourist site in County Cavan.

Doonagore Castle

The Doonagore castle was originally built as a stone structure dating back to the 14th century.

In the 16th century, most of this original structure was replaced with new constructions which included a huge enclosure wall lined with numerous towers.

The 16th century construction of the castle was done by the O’Briens clan but the clan soon lost its control to the Clancys.

Located in County Clare, the castle underwent nearly a century of abandonment and decline before it was finally restored and preserved in the 20th century.

Today, the castle is open to visitors and is a popular attraction in the county.

O’Dea Castle

The O’Dea castle was constructed by Diarmaid O’Dea in the 15th century.

It supported an unusual architecture for its time, hosting a huge tower which rose to the height of 50 feet.

The O’Dea clan lost control of the castle briefly in the 16th century but regained it soon after.

During the time of James II, the O’Dea clan decided to support the James II cause, and with James’ failure, the family also lost the castle and the territory.

The castle lay in ruins for nearly two centuries but then underwent significant restoration in the late 20th century.

Most of the original structure of the castle is extant today and is open to visitors.

Knappogue Castle

The Knappogue castle dates back to the 15th century when it was constructed by the MacNamara clan as a tower house with fortifications.

However, it remained only briefly in the hands of Cromwellian authorities and returned back to the MacNamara control in the 17th century.

It played an important role during the War of Independence in the 20th century.

Today, the castle is owned by the Irish government and stands well-preserved. It is open to visitors and tourists.
