Portaferry Castle

Portaferry Castle is a square tower house in Portaferry, Northern Ireland, standing three stories tall with an additional attic level and featuring a projecting turret at its southeastern corner. The structure displays the compact, functional design typical of defensive towers built to guard harbor settlements during the early modern period.

William Le Savage initiated construction of this defensive tower in the early 16th century to protect the strategically important harbor below. The structure formed part of the regional defense system designed to guard against threats approaching from the sea.

The castle incorporates medieval defensive elements such as a murder hole and machicolation, reflecting the architectural practices of Northern Irish fortifications.

Entry proceeds through a ground-floor turret passage that connects to a curved stairway leading to the main chamber above. The interior spaces are compact and the walls are quite solid, so visitors should expect a tight layout with limited room to move around.

From its position, visitors can spot both Strangford Castle and Audley's Castle across the waters of Strangford Lough. This vantage point reveals how the fortified towers could keep watch over one another across the waterway.
