Overview
Drimnagh Castle is a medieval stronghold with a water-filled moat, fed by a small stream called the Bluebell and crossed by a stone bridge built in 1780 to replace the original drawbridge. It sits on Long Mile Road in Dublin 12, six kilometres from the city centre, and although the farmland around it became a 1930s suburb, the castle survived and was restored. It offers guided tours and limited self-guided hours.
History and legends
The lands of Drimnagh and Terenure were granted by King John to the de Berneval family, later anglicised to Barnewall, in 1215, and the Barnewall family held the castle for centuries. The name itself comes from the Irish Droimeanach, ‘ridged land’, and there is evidence of people here long before the Normans arrived.
The Barnewalls’ loyalty to the Crown during the 1641 rebellion won them further land grants. By the 18th and 19th centuries, though, the castle had slid into use as a farmyard and lost much of its detail, before a 20th-century restoration rebuilt the great hall and battlements and refilled the moat.
Folklore clings to the place. Guides tell of Elanora, a young girl of the Barnewall family said to have died in the castle and to haunt it still.
What to see and do
The features worth your attention:
- The moat and bridge – Walk the circuit to see the water-filled moat, fed by the Bluebell and crossed by the 1780 bridge.
- The murder hole – Above the gateway in the entrance tower is a ‘murder hole’, through which defenders could pour rocks, boiling water or lime on anyone trying to force the gate.
- The Great Hall – The centrepiece of the restored interior. In the 13th century it was a multipurpose room: tables and benches for dining by day, straw matting for sleeping at night.
- The undercroft – A vaulted lower chamber used for food storage and refuge, now holding a recreated 19th-century kitchen with a bread and smoking oven. Note the stairs, which turn left, unusual for a Norman castle.
- The formal garden – A restored symmetrical garden, a quiet place to walk after the tour.
