Donegal Castle – A True Gaelic Masterpiece (History, Interesting Facts & Travel Tips)

-

In the heart of Donegal Town, Ireland stands the 15th-century marvel – Donegal Castle. It was built by Sir Red Hugh O’Donnell and has been associated with numerous influential clans of Ulster for almost 11 centuries. 

It is said that the site of this castle was once the grounds of a Viking stronghold – hence the moniker “Fortress of the Foreigner.” The structure of Donegal had succumbed to the tides of time over the centuries, but the ruins were restructured and turned into a nice visiting place in the latter half of the twentieth century. Let’s talk a bit more about it:

Early History

Construction & Influence of the Donegal Castle

Donegal Castle was commissioned by Sir Red Hugh O’Donnell in 1474. He was the ruler of Tyroconnel and head of the O’Donnell family – one of the very last chieftains of the Gaelic command. The castle sits proudly atop the mountainous curves that loom above the River of Eske and was originally constructed to house the O’Donnell family.

The O’Donnells were one of the last Irish clans to stand against the English. The castle was also, at one time an important fortification to the Lords of Tír Conaill. The aristocratic influence of these families spanned across many centuries, impacting the historical significance of this fortification.

The 16th Century Appreciation

The Donegal castle is a sheer masterpiece of Gaelic craftsmanship. Over the centuries, it has been appreciated by many, including Sir Henry Sidney, English Viceroy. He quoted in his 1566 report that the castle was one of the greatest that he had ever seen, also noting its sturdy foundation and architecture.

Flight of the O’Donnells

The Donegal castle has a very sordid history. Its inhabitants, the O’Donnell’s, left Ireland in 1607 (right after the Nine Years War) during the Flight of the Earls. However, Hugh O’Donnell didn’t want his castle falling into English hands, so it’s believed that he set it on fire.

Palace Granted to Basil Brooke

The castle had been seriously harmed by the leaving O’Donnell’s to forestall its use against the Gaelic families. However, its new owners sought out an immediate renovation in 1611, when Donegal and its properties were handed over to an English Captain, Basil Brooke. This new proprietor was all about maintaining the original Jacobean integrity of Donegal’s structure, so all the additions that he made were in cognizance of that style. From the brand new windows to an enormous villa wing, everything complemented the contextual fabric of the castle’s original style.

The Brooke family held ownership of the palace for quite some time, but then it started to disintegrate because of terrible maintenance. It wasn’t until 1898 when the Earl of Arran had it transferred to the Office of Public Works, that restoration was able to begin in the first decade of the 20th century.

Current Times

The Office of Public Works has since remodeled the palace to make contemporary use out of it. With new materials and an added deck – both of which complement the authentic styling of this building – it’s become a modern-day tourist attraction. Other revamped sections include the stonework and the roofing of the east wing. The oak work used in it was actually derived from the Brookeborough Estate, which is located in County Fermanagh. The palace is currently open to people in general and regularly hosts events like the Gaelic Social Nights.
