Dunseverick Castle

Dunseverick Castle comprises fortress ruins positioned on a basalt promontory along the Causeway Coast, with fragmentary walls rising from rocky cliffs. The remains occupy a headland location that offered defensive advantage and control over coastal waters.

The fortress was originally built as a stone structure in the 5th century and faced Viking raids around 870 AD. It later became a key stronghold for the Earls of Ulster, serving as a strategic point on the northern coast for centuries.

The site held religious significance in medieval times, drawing pilgrims seeking connection to its sacred past. Local communities valued it as a place where spiritual and military power intertwined in early Irish society.

The National Trust maintains these ruins, accessible via the Causeway Cliff Path connecting Dunseverick Harbor to Giant's Causeway. The route is walkable on foot but traverses rocky terrain and coastal conditions that can become demanding depending on the weather.

The ruins marked the northern endpoint of Slige Midluachra, one of five ancient royal roads connecting to Tara, the seat of Irish kings. This connection shows how vital this coastal location was to early Irish trade networks and political structures.
