Dundrum Castle

Northern Ireland, Ireland

---

Dundrum Castle in Northern Ireland was built around 1177 by John de Courcy, a Norman knight who invaded and conquered Ulster.

The castle occupies a strategically important position on a rocky hill overlooking Dundrum Bay and features a large circular keep, thick walls, and a gatehouse. Its design reflects Norman military architecture focused on strong defense. Throughout its history, Dundrum Castle played a significant role in controlling the surrounding area, changing hands among powerful clans and figures like the Magennis clan and the Earl of Kildare.

During the 17th century, it was partially dismantled by Oliver Cromwell’s forces. Today, the castle stands as a well-preserved ruin and historic landmark offering visitors panoramic views and a glimpse into Northern Ireland's medieval past.
