A Brief History of Irish Castles

We love castles because they are windows into our Irish culture and heritage.

Castles first started appearing in the 9th or 10th century, and some were built so sturdily that parts of them survive more than 1,000 years later.

In several ways, life back then was a never-ending battle. Local lords were always looking over their shoulders, worrying about which neighbors would launch the next attack.

So they built big, heavily fortified stone castles with arrow slits, towers, battlements and stone walls that are several feet thick, to protect themselves.

Irish castles weren’t just forts, though. They were also the homes of the Irish lords, and they were luxurious for their era. Many featured moats – watery channels surrounding the castles.

Beautiful tapestries and other wall hangings adorned the stone walls. They also deadened the echoes that otherwise would have reverberated throughout the rooms. Luxury and comfort were important, as was impressing (sometimes intimidating) visiting guests.

Today most Irish castles are in ruins, which in some ways makes them even more interesting. Some have been restored to various degrees. Some have been fully restored, and transformed into tourist attractions or even hotels - perfect for Ireland castle vacations.
