Knappogue Castle, Tower house museum in County Clare, Ireland.

Knappogue Castle is a grey stone tower house built in 1467 in Quin, County Clare, with a crenellated parapet of stepped merlons and a corner turret. Vertical slit windows and two grouped rectangular windows sit on its facade, and a lower crenellated wall with three multi-paned windows and an arched doorway runs across the front. Mid-19th-century additions by the Pain brothers include a drawing-room, long room, west wing, clock tower and gateway.

The castle was built in 1467 and served as a defensive stronghold during the Irish Confederate Wars until it was taken over during the Cromwellian invasion. These conflicts shaped its role as a military post in a period of upheaval.

The castle hosts medieval banquets where visitors enjoy traditional Irish music and local cuisine in the grand dining hall. These events keep alive the way the fortress once served as a gathering place for celebration and community.

Guided tours of the restored tower house are offered; the castle also serves as a venue for weddings and medieval banquets. The 1817 walled garden, about 0.5 hectares, has been returned to its earlier layout and its walls replanted with climbing roses, grapevines and clematis. Visitors reach the site in Quin parish, County Clare, by road.

The whiskey sold under the name "Knappogue Castle" is not made here: it is produced by the Castle Brands company, which bottles spirit made by Bushmills. The castle itself is a venue for weddings and medieval banquets.
