Overview
Kanturk Castle is a great house that was never finished, and never roofed. Begun for MacDonagh MacCarthy, Lord of Duhallow, around 1600, it was rising fast, a limestone block of four storeys with a five-storey tower at each corner, when the English Privy Council, alarmed at the scale of it, ordered the work stopped in 1618. It has stood open to the sky ever since, on a low rise just south of Kanturk with the Duhallow farmland spread out below. It is a National Monument, free to walk up to, and one of the more atmospheric ruins in north-west County Cork.
A fortress interrupted
The castle, known locally as the Old Court, was built as a chief residence and stronghold for the MacCarthys against the English planters pushing into Munster. The rectangular block runs 28 m by 11 m and rises four storeys; the four corner towers climb five storeys to about 29 m. It is all local limestone, quarried just north of the site. The design hedges its bets between two worlds: traditional Irish tower-house features like pointed-arch windows and rear gun loops, set against fashionable Tudor and Renaissance touches, above all the finely carved limestone door surround on the north front, with its pilasters, round arch and classical frieze.
Then it stopped. Fearing a fortress ‘much too large for a subject’, the Privy Council halted construction in 1618, and the castle was never completed or roofed. Legend has it that MacCarthy, in a rage, smashed the blue ceramic tiles meant for the roof and flung them into the stream below, which has been the Bluepool ever since. The castle passed through the Perceval family and the Earls of Egmont, and in 1900 the Countess of Egmont gave it to the National Trust on the condition that it stay a ruin. Until 2000 it was the only property the Trust held outside Britain, when it passed to An Taisce, in whose care it remains.
What to see
Because the interior is unroofed and unsafe, the visit is really about walking the outside and reading the stonework:
- The corner towers – massively built and fully corbelled, they show how the defensive plan was meant to work.
- The Renaissance doorway – on the north face, among the best early-1600s classical carving in rural Cork, and the single feature worth crossing the field for.
- The fireplaces – several survive in the shell, the third-storey one with a boldly carved mantel.
- The clash of styles – Irish pointed arches beside Tudor mullioned windows, the architecture caught between Gaelic Ireland and the incoming English fashion.
From the foot of the towers the ground falls away towards the meeting of the Allow and Dalua rivers. On-site panels fill in the history.
Practical information
The castle is open all year and free, external viewing only, as the interior is closed off and structurally unsafe. A small lay-by beside the ruin gives free parking. There are no toilets, café or shop, so come prepared. The ground is uneven and scattered with loose stone, worse after rain, so wear proper shoes and keep back from the tower bases. It is not wheelchair accessible. Dogs are welcome on a lead.
For photographs, early morning or late afternoon is best, when low sun brings out the texture of the limestone.
Getting there and around
Kanturk is about 50 km from Cork, just north of the N72. The nearest railway station is Banteer, some 6 km away, and Bus Éireann route 243 links Kanturk with Mallow and Cork city; from the bus stop in town it is a 20-minute walk out to the castle. On foot or by bike, the site sits on the Duhallow Way. For a fuller day, pair it with Doneraile Court and its estate, about 22 km east, or a wander in the Ballyhoura hills.
