Dublin Professor Uncovers 13th-Century Castle Hidden Inside Modern University Building
A medieval castle thought lost for centuries was discovered intact within a Victorian-era building at University College Dublin. Professor Tadhg O’Keeffe identified the structure by analyzing 18th-century watercolors and recognizing architectural clues like thick walls and splayed windows. The discovery, announced in September 2026, reveals that 70-80% of the original Roebuck Castle survives beneath modern plaster, offering a rare glimpse into Ireland’s Norman-era history.
