From the Irish Examiner:
It feels like glorious serendipity that a project aimed at revealing more about the only woman known to have built a castle in Ireland is taking place during National Heritage Week.
I’m a huge fan of castles and, in particular, of castlebuilder Roesia de Verdun, or Rose of the Rock as she is known locally. The 13th-century noblewoman built an impressive fortress on a rocky outcrop in Castleroche, Co Louth, and then supposedly pushed the master mason out of the window so that he wouldn’t replicate the building’s design.
To this day, one of the castle’s windows is known as the “murder hole”.
Once ensconced in palatial splendour, the formidable Roesia went about her business as a no-nonsense châtelaine, managing her estate and riding out on horseback, in full armour, to keep her Gaelic enemies at bay. Or so the local legend tells us.
