Raphoe Castle, Historical castle in Raphoe, Ireland

Raphoe Castle is a stone fortress at the edge of town with remains from the 17th century, built to serve as both a bishop's home and a defensive structure. The layout shows the typical features of a fortification from that period.

Raphoe Castle was built in the 1630s for John Leslie, Church of Ireland Lord Bishop of Raphoe, using stone from a ruined round tower. Leslie was besieged in it during the Irish Rebellion of 1641 until the Laggan Army relieved him, and the castle surrendered to besiegers in 1650 during the Cromwellian conquest. Supporters of James II damaged it in 1689, United Irishmen attacked it in 1798, and an accidental fire destroyed it in 1838.

The building shows how religious and military power were linked in Irish society, serving as both a bishop's home and a fortress at the same time. Walking through the site, you can still see how these two roles shaped what was built.

The castle ruin stands at the edge of Raphoe, County Donegal, and can be reached on foot from the town centre. The sources record no opening hours, admission arrangements or on-site signage, so check locally before travelling. The surviving walls are roofless and exposed to the weather.

Stone from a demolished round tower in the area was reused in the castle's construction, creating a direct link to earlier medieval structures. This practice was common and shows how older buildings were incorporated into new projects.
