Overview

Macroom “Castle” is really two pieces: a theatrical gatehouse on the West Square that you can walk straight through, and a ruined riverside block, a three-storey square tower and the western façade of a lost west wing, standing above the River Sullane. Don’t come expecting a castle to tour. The main residential building was demolished in 1967 and replaced by a wing of Bishop McEgan College, and what’s left is set in a free public park held in trust for the town, open all year.

The gatehouse is the piece everyone photographs: an arched passage flanked by round turrets, low crenellated walls and two cannons on pedestals, put up in the early 19th century by Robert Hedges Eyre as a romantic flourish for the town centre. Downriver, the tower rises three storeys, its crenellated roof and hood-moulded windows the product of 19th-century rebuilding around a much older core. If you have half an hour in Macroom, walk through the gatehouse and down to the riverside path. That’s the castle, and it’s worth the short loop.

A turbulent history

The castle probably dates to the reign of King John in the early 13th century, though the earliest owners are uncertain: the O’Flynns, the Carews or the Daltons all appear in the record. The Irish name Caisleán Uí Fhloinn keeps the O’Flynns’ memory. In 1353 the castle and its lands were granted to Dermot MacCarthy, first Lord of Muskerry, and the MacCarthys held it, with interruptions, until the Williamite wars.

The 1600s were hard on the place. Government forces under Captain Flower, and later Charles Wilmot, besieged it, taking the stronghold after an accidental fire. In the 1640s the Papal Nuncio Rinuccini was received here by Lady Muskerry and her eleven-year-old son. Under the Cromwellian conquest, Bishop Boetius McEgan gathered a Confederate army inside the walls in 1650; the garrison fired the building before marching out, and the battle that followed ended with the bishop captured and hanged at Carrigadrohid.

After the Restoration the estate went back to Donough MacCarty, now 1st Earl of Clancarty, who enlarged the house. It later passed to Admiral William Penn, father of the founder of Pennsylvania, then to the Hollow Sword Blade Company, and on to the Bernard family, later Earls of Bandon. Robert Hedges Eyre reshaped the town centre in the early 19th century and added the gatehouse.

The 20th century brought more fire. British Auxiliaries used the site in the War of Independence, and anti-treaty forces burned the castle on 18 August 1922 during the Civil War. The demesne was sold to a local trust in 1924, for the town. An armorial plaque salvaged from the castle is now kept in Macroom Museum, and the last private owner, Olive White, married Arthur Guinness of the brewing family.

What to see and do

The gatehouse
Walk through the arched passage and look up at the guard chamber above it. The round turrets, slate façade and pair of cannons give it a deliberately medieval look, and it’s open to walk through at any hour.

The tower and west façade
The three-storey tower, with its 19th-century crenellations, shows the line of the older core. The western façade, five bays with a projecting centre, a pointed-arch gate, crow-stepped gable and hood-moulded windows, is later Gothic-revival work. It stands on a steep bank just above the Sullane bridge; the best view is from the riverside path or Castle Street.

The demesne
The grounds are a public park along the river, with mature oak and beech, benches, picnic space, playgrounds and ball fields, and riverside walks. It’s well used by families and dog walkers.

Nearby
South of the town, The Gearagh is a rare alluvial forest reserve worth an hour. Gougane Barra Forest Park and the Gaeltacht village of Ballyvourney lie to the west; for modern history, Béal na Bláth, where Michael Collins was ambushed in 1922, is a short drive out.

Practical information

Access and admission
Free, open daily dawn to dusk. The grounds are a public park and the gatehouse can be walked through without restriction. There are no indoor facilities or guided tours on site.

Getting there
Macroom is about 40 minutes by car from Cork city and airport on the N22. Bus Éireann route 233 runs from Cork (Parnell Place), taking roughly an hour and a quarter. The old railway station closed in 1935. In town, the castle sits on the western side of the central square, a short walk from the main street and the Sullane bridge. There’s free parking at the rear of the Castle Hotel and on-street spaces nearby.

When to go
Weekdays are quieter. The Macroom farmers’ market runs on Tuesday mornings and is worth timing a visit around, and early or late in the day the low light on the stone is best for photographs.
