Top 10 best castles in Ireland, RANKED

They are planted on or in Irish river banks, rocky coastlines, and wooded parklands – here are the best castles in Ireland ranked from ten to one.

Ireland’s history is a famous and well-known one, and its landscape has been moulded by the footmarks of Irish kings and British royals gone-by, leaving behind them a wounded nation but a series of remarkable castles.

Ireland is now a Republic and castles no longer host the seat of power. However, with over 30,000 spread across the country, they enrich the scenery and leave us in awe of their structure.

Here are the top 10 best castles in Ireland, ranked.

Kicking off our list of the best castles in Ireland is the Blarney Castle in Cork, famous for the ‘Blarney Stone’ that can be found at the top of the castle. It is said that kissing the stone bestows upon you the ‘gift of the gab’. This is a must to visit when backpacking Ireland.

Irish chieftain Cormac MacCarthy constructed this castle over six hundred years ago, and while its appearance has decayed, its brilliance as a structure has not diminished.

Address: Monacnapa, Blarney, Co. Cork, Ireland

Moving northwards and into Limerick city, we have King John’s Castle, which casts its eye over the River Shannon as it flows silently by.

The castle is even older than Blarney, having been built 800 years ago, and even recovered from severe damage incurred during the 1642 Siege of Limerick, making it an essential on an Irish road trip.

Address: Nicholas St, Limerick, Ireland

8. Castle Saunderson (Co. Cavan) – the castle ruins

Castle Saunderson is now a Scouting Ireland facility.

Castle Saunderson in County Cavan was originally in the hands of the O’Reilly’s of Breffini before the Saunderson family acquired it during the Plantation of Ulster.

Covering 34 acres in total, the grounds now act as a Scouting Ireland facility. This has been in operation since 2012, and the grounds are open to Scouts year-round.

Cahir Castle is one of Ireland’s best-preserved castles, no mean feat as it has featured in Irish society since the 13th-century.

Conor O’Brien, Prince of Thomond, built it, and its opportune location is evidenced by its flirtation with the River Suir.

Ashford Castle is one of the best castles in Ireland.

Surrounded by gorgeous green-land and still river water, the five-star luxury hotel in the West of Ireland has been transformed into a modern-day masterpiece.
