A Guide To Donegal Castle: Tour, History + Unique Features

A Guide To Donegal Castle: Tour, History + Unique Features

A visit to the mighty Donegal Castle is one of the most popular things to do in Donegal Town.

For two centuries, Donegal Castle laid in ruin and it wasn’t until the 1990s that the castle was restored to its former glory – it’s now one of the most impressive castles in Donegal.

Frankly, it’s a miracle the castle is still standing, especially with such a turbulent history, then again it was once home to one of the most powerful families in Ireland, the fearsome O’Donnell’s, so it was made to last and hopefully will stay that way. 

In the guide below, you’ll find everything from Donegal Castle facts to everything you need to know about the tour and more.

Donegal Castle History

It is said that when Donegal Castle was originally built, it was the most impressive of the many Irish castles the island boasted at the time.

While the castle has been home to only two families over the years, both have played a vital role in Irish history.

The O’Donnell’s, who built the castle in 1474, ruled one of the biggest territories in Ireland known as Tyrconnell at that time (mostly made up of Donegal and neighboring counties).

An unlikely alliance and many a battle

In the 1580s, the O’Donnell’s joined forces with the O’Neill’s (a lifelong enemy of the clan) as there was threat of their lands being seized by the crown.

Red Hugh O’Donnell, who led the battles against the English was victorious for a short period but eventually lost to the English at the Battle of Kinsale in 1602.

This resulted in Red Hugh and many other Irish Chieftains leaving Ireland for Spain, an exodus known as ‘The Flight of the Earls’. The rest of the O’Donnell clan held on as best as they could but this was to change.

The English and a journey to restoration

In 1611, the crown took control of all estates that belonged to the O’Donnell clan and gifted the castle to English Captain Sir Basil Brooke.

Brooke began modernising it at once, adding windows, a manor house extension and a banquet hall.

The Brookes owned the castle until the 1670s before selling it to the Gore Dynasty, resulting in the castle falling into ruins in the 18th century.

In 1898, the castle was donated to the Office of Public Works who began restoring the castle in the 1990s.

There’s a reason the Donegal Castle tour is regarded by many as one of the best things to do in Donegal – it’s excellent!

If you plan one doing the Donegal Castle tour, there are a number of things that you should keep an eye out for.

1. The Courtyard

When you are in the courtyard of Donegal Castle, you’ll have your first chance to admire many of the castles interesting features. The Celtic keep has some unusual medications made for one and you can spot the ruins of the manor-house, made in a Jacobean style.

2. History room

On the top floor of Donegal Castle is where you will find the History Room, full of displays where you can learn a great deal about the most powerful family in Ireland, the O’Donnell’s. There is also scale models of Donegal Castle so you might discover something you missed.

3. The Old Trip Stairs

The Trip Stairs are my favourite feature on the Donegal Castle tour. This 543 year old spiral stairway is made entirely by stone.Designed by the O’Donnell Chieftain who made the steps uneven and in varying heights to trip any unsuspecting invader.

As the stair goes clockwise going up, this would give O’Donnell’s more leeway when fighting (as they were right-handed).

4. The Beautiful Stonework

The walls in Donegal Castle are made from stone and made in such a gothic-like intricate way, the attention to detail is thought-provoking. The underfoot is also impressive, made from a perfectly smooth paved stone.

5. The Mast

Yes, there is a mast from an old ship in Donegal Castle, it’s white sail has turned yellow over the years. When the O’Donnell’s were in charge, Donegal Town was a thriving hub for international business and ships often delivered cargo to the wharf close to the castle.

6. The Banqueting Hall

And the final thing to keep an eye out for on the Donegal Castle tour is the Banqueting Hall. The huge fireplace bearing the Brooke family arms and stuffed wild boar head on the wall make this seem like a place where many a fine meal was had.
