Discover more about Mongavlin Castle

Mongavlin Castle, also known as Mongevlin Castle, stands in ruin on the west bank of the River Foyle, approximately 3 km south of St Johnston, County Donegal. This location was once a strategic stronghold, witnessing centuries of Irish and Scottish history. In the 16th century, Mongavlin was the chief residence of Iníon Dubh (the Black Haired Daughter), the mother of Red Hugh O'Donnell. This formidable woman, a Scottish princess from the MacDonald clan, played a significant role in Ulster politics. She brought Scottish warriors, many named Crawford, to protect her, and their descendants still live in the area. The castle later came into the possession of Sir John Stewart, an illegitimate son of the Duke of Lennox, who constructed a strong castle in 1619. Over the centuries, Mongavlin Castle has been a site of sieges, political intrigue, and clan warfare. King James II visited Mongavlin in 1690 on his way to the Siege of Derry. He sent a letter from here proposing surrender, but it was rejected. Today, only a portion of the castle remains, a testament to its tumultuous past. Visitors can explore the ruins and imagine the lives of those who once walked its halls, while enjoying the scenic beauty of the River Foyle.
