Once a grand Anglo-Norman castle, Carlow Castle is now a simple ruin standing on the eastern bank of the River Barrow. It was once an important and strong military fortress that served strategic importance due to its location. All that stands of it today is two battered towers and part of an intervening wall. While only a small ruin, it still boasts a certain sense of extravagance.
The history of Carlow Castle
Carlow Castle is a beautiful castle situated in the town of Carlow. It is said to be one of the most important Anglo-Norman castles in all of Ireland. It is now open to the public and still offers breathtaking views and a glimpse into history. Nowadays, it is a National Monument of Ireland.
The early history
The first-known written record of Carlow Castle is from the year 1231. However, the name of the builder has never been officially stated. Many people throughout time believe that the castle was built by William Marshal the elder sometime between 1207 and 1214. It was during those years that he spent time in Ireland.
Building Carlow Castle
Carlow Castle was the first of its kind in Ireland. The reason being that it consisted of a towered keep with a massive rectangular tower surrounded by four smaller three-quarter-circular towers at each corner of the rectangle. It is said that many doubted the castle because they believed it did not support the traditional function of a keep (to serve as a refuge of last resort).
Instead, the keep diverted from the contemporary standard in England and continental Europe. For example, there was no towered curtain, no gatehouse, and no undivided great hall. There were very few castles erected in the same period.
In 1306, the castle was handed over to the crown. Then, in 1312, it was granted to Thomas Plantagenet until it was once again confiscated by the crown in 1537 due to the landlord being absent. Once again, in 1616, it changed hands when it was purchased by the Earl of Thomond.
Carlow Castle continued to change hands until it was taken over by Oliver Cromwell in 1650 and taken once again by the Earl of Thomond not long after. The castle was partially destroyed in the year 1814 after an attempt to create more space within the castle for a lunatic asylum. Explosives were used and unfortunately, they had the opposite effect by widely destroying the castle.
Only the west wall and two of the neighbouring towers were able to be preserved.
The current day
Carlow Castle now welcomes many visitors to the grounds every year. While it has never been rebuilt or remodelled, it is still a beautiful place to visit. With picturesque views, lovely attractions nearby, and a deep history, there is no better place to see while visiting Ireland.
