McDermott Castle, Republic of Ireland, Ireland

McDermott Castle

Republic of Ireland, Ireland

McDermott Castle, also known as McDermott’s Castle, stands on a small island in Lough Key, County Roscommon, and is one of Ireland’s most picturesque castle ruins.

It was the stronghold of the MacDermott clan, rulers of the medieval kingdom of Moylurg, and the island has been fortified since at least the 12th century. The castle played an important role in regional conflicts and was attacked several times during the medieval period, including during the Anglo-Norman conquest of Connacht in 1235.

Over the centuries, the original fortress was rebuilt and altered, with much of the structure visible today dating from renovations carried out in the 19th century. Surrounded by the scenic waters of Lough Key, the castle is also linked to local legends and folklore, including stories of the MacDermott family and tragic romance. Today, it remains one of County Roscommon’s most iconic landmarks and a striking symbol of Ireland’s medieval heritage.
