It has faced fire and abandonment. This place attracts history fans and adventurers to uncover its secrets. In this post, we’ll explore what makes McDermott’s Castle a must-see place and everything you need to know before you make your plan.

History and Origins

McDermott’s Castle has a long history dating back to when the McDermott clan ruled the area around Lough Key. They were a powerful Gaelic family and they had significant influence in Connacht during the Middle Ages. As leaders of Moylurg, they chose Castle Island as their base because the lake provided them natural defenses.

The first stone castle was built on the island in the 12th century. It served as a defensive structure for the McDermott clan against many rival groups. The location gave them absolute control over the lake’s waterways.

In Thirteenth century, an Anglo-Norman baron named Richard de Burgh invaded and destroyed the castle. But the McDermotts rebuilt it and transform it into a fortified residence.

Over the centuries the family used the castle to strengthen their rule. By the 17th century, their power had weakened and the castle fell into disrepair.

Today, McDermott’s Castle is a reminder of the family’s history and gives us a glimpse into medieval Ireland.

McDermott’s Castle though mostly in ruins today still shows intriguing hint of its past. The most recent structure on Castle Island was built in the 19th century with a romantic Gothic Revival-style residence by replacing the older medieval fortress.

Inside the grand rooms recall a period of aristocratic luxury. The main hall has high ceilings and big windows that frame beautiful views of Lough Key. Once there guests were entertained.

McDermott’s Castle stands out because of its unique location. It is nestled on a tiny island in the middle of the water. That’s why it feels both isolated and deeply connected to the natural beauty of Lough Key.

Local legends and stories

McDermott’s Castle is wrapped in centuries-old legends. A legend says that Úna Bhán the daughter of the McDermott chief fell in love with a lower-class boy. At that time, this was unacceptable, so her father locked her from leaving the island. The story claims that her boyfriend swam to Castle Island to see her but drowned one day while swimming. Úna died of a broken heart and the two are said to be buried on the island under two intertwined trees that grew over them. This local legend is famous in the area and has appeared in different types of literature over the years.

Another story tells of a fire that burned down the castle. Supposedly was caused by lightning. The McDermott family thought the gods were punishing them. So, they promised to rebuild the castle and made offerings to prevent another disaster.
