Let’s delve deeper into this captivating landmark and uncover the secrets it holds.

A Journey Through Time | History

McDermott’s Castle is a relic of an ancient past, its origins dating as far back as 1184. At that time, Ireland was divided into numerous kingdoms, each ruled by powerful clans.

The castle was constructed by the McDermott clan, the dominant family in the region for over five centuries. Due to the limited space on the island—just 0.57 acres—the clan maintained another residence on the mainland near Moylurg Tower. Unfortunately, during World War II, a lightning strike caused a fire that left the castle in ruins.

Primarily, the castle served as a fort during battles with rival clans and invasions by the English. Despite its strategic location on the island, McDermott’s Castle could not escape destruction and decay.

By the 17th century, during Cromwell’s conquest of Ireland, the land fell under English rule. In the 18th century, the castle and island were transformed into a venue for royal entertainment and leisure. Later, in the 19th century, the property was acquired by renowned Welsh architect John Nash, who left his mark on its design. Eventually, in the 20th century, the castle returned to Irish ownership, where it remains a treasured historical landmark.

Legends and Lore

Beyond its storied history, McDermott’s Castle is steeped in a haunting tale of love and loss—the legend of Úna Bhán.

Úna, the beautiful daughter of the McDermott clan chief, fell deeply in love with Tomás Láidir, a nobleman from a rival clan. However, her father disapproved of their union, deeming Tomás unworthy of his daughter. Forbidden from being together, the couple was forced to keep their love a secret.

Tomás would swim across the waters of Lough Key to reach the castle and see Úna. Tragically, during one of these daring swims, he drowned in the lake’s cold embrace. Devastated by the loss of her beloved, Úna succumbed to her grief and passed away shortly after.

Legend has it that their spirits still linger around the castle ruins, bound together by an eternal love and the tragedy that ended their story. Some visitors claim to feel their presence, a bittersweet reminder of a romance that defied the odds but fell victim to fate.
