Mcdermott’s castle In Roscommon- Everything You Need to Know About Mcdermott’s Castle

Mcdermott’s Castle is located on a small island in the middle of Lough Key Lake in the County Roscommon, Ireland. It is recognized as a protected national monument. The Castle is now a historical ruin, but once it was the stronghold of the Mcdermott clan. In this article, we’ll explore what makes this Castle a must-see place.

Historical Background

Mcdermott’s Castle has a long history. The first time it was mentioned in history is around the 1200s. At that time, Ireland was divided into many kingdoms.  The McDermott clan was the ruler of that particular region at that time. They build this Castle as a defensive stronghold of the McDermott clan.

The Mcdermott’s were a powerful Gaelic family who ruled the surrounding area of Moylurg for five long centuries. They also had another residence on the mainland near Moylurg Tower, as space was limited on the island.

This Castle was mainly used as a fort for the battles between rival clans and Others. Though having a strategic location, Mcdermott’s Castle couldn’t keep itself safe from getting ruined.

In the Thirteenth Century, Richard de Burgh invaded and destroyed the Castle. Later, the Mcdermott’s rebuilt it and transformed it into a fortified residence.

Over the centuries, the family has used the Castle to strengthen their rule. Here’s a brief description about this fort by period.

17th Century

  • The power of the Mcdermott clan weakened, and the castle fell into disuse. The whole land became property of England during the rule of Oliver Cromwell.

18th Century

  • The site was used as a location for entertainment for the royal family.

19th Century

  • Architect John Nash acquired Castle Island and introduced architectural changes to the castle.

20th Century

  • The castle became the property of Ireland.

As of today, it is recognized as a protected national monument.

A tale of tragedy

The castle has a painful, tragic history.  One of the most well-known legends of the  Mcdermott’s Castle is the tale of Una Mcdermott, a young woman from the McDermott clan. 

Una was the beautiful daughter of Mcdermott. She fell in love with Tomas Laidir. He was a nobleman from a rival clan.

Una’s father believed the boy wasn’t good enough for her daughter. As he was from a rival clan, Una’s father forbade her from meeting with him. So they had to keep their affair secret. 

One day, Una’s father discovers the truth about their relationship.  Her father locked her from leaving the island. Hearing that, her boyfriend swam to Castle Island to see her but drowned while swimming. 

Una also died from the grief of her partner. Local people believe their spirits still roam in the ruined castle.

When to Visit Mcdermott’s Castle

As the island is privately owned and protected as a national monument, it mostly remains empty and abandoned. But when you look at the castle, you can imagine the lives of those who once called it home.
