Just 5 miles west of Newport, Ireland, lies the 16th-century tower house Rockfleet Castle. The imposing tower was once part of a larger, square-shaped castle that was occupied by 1 family. Grace O'Malley, a powerful pirate during the 1560s, desired Rockfleet Castle as a hideout from the British forces. To obtain it, she married its owner, Richard Bourke, with plans of immediate divorce. In a shocking twist, she actually fell in love with him. Grace was never captured by the English, and eventually, she and her husband became the most powerful couple in northwestern Ireland.
