Lost in the middle of Lough Key lake is a small island and its castle: Castle Island (also known as Macdermott’s Castle). Magnificent, it once belonged to the most influential family in the Roscommon region and is one of the jewels of the lake. The only way to admire it is by boat!

There are still many mysteries surrounding this castle. However, it is thought to have been built around the 12th century. Its installation on an island in Lough Key ensured its occupants peace, security and a 360-degree view of the surrounding area: an ideal location for keeping an eye on their Kingdom!
Unfortunately, the building was struck by a terrible fire, causing death and destruction within the castle.
After this tragedy, the castle was rebuilt, and the current château dates from the 18th century. Although most of the castle is in ruins, some magnificent features are still intact.
Now in a state of ruin, the site is still the object of great fascination for tourists and historians alike. The castle is still clearly recognizable, with its fortified enclosures, high tower and crenellated defensive walls!
The château stretches high up on a tiny island, surrounded by local woodland. This gives it an authentic, picturesque charm!
Note that a large part of the island is completely overgrown with ivy, and difficult to access in places. The nearby islands are home to ruined churches, towers and priories, and it is also thought that many unmarked or lost graves are scattered around.
Be sure to explore them: they add to the beauty and magic of the region.
As well as being a must-see historic castle, the building is also said to be the bearer of a terrible legend: that of Úna Bhán.
To better understand, Úna was the daughter of the head of the McDermott clan, whose name is the origin of the castle.
Úna had fallen in love with a boy who, according to her father, was not good enough for her. Despite being forbidden to see him again, she began a secret affair with her lover.
Legend has it that the boy regularly swam across the lake to Úna… Unfortunately, on the occasion of his umpteenth visit, he didn’t make it and drowned in the waters of Lough Key.
Úna would have died of a broken heart. According to legend, the couple were buried on Trinity Island, another island in Lough Key, not far from the castle. Two trees would have grown over their graves, intertwining to form a lovers’ knot. As dramatic as it is romantic, isn’t it?
Lough Key Park and Estate are open all year round for the public to explore, and daily boat trips are organized throughout the year across Lough Key. Allow around €10 for the visit.
The region is never overflowing with visitors. We therefore advise you to visit when the weather is good, so you can discover Lough Key and McDermott’s Castle in the best possible conditions!
