Overview
Coollattin Estate sits on the gentle slopes of Shillelagh in County Wicklow, where centuries of land management have shaped a landscape defined by mature oak woodlands, winding footpaths, and open views. Today, the estate is best known for its premier arboretum golf course, but the grounds hold a much deeper story. From 17th-century English aristocracy to 19th-century famine scholarship, Coollattin offers a quiet but compelling look at how Irish landownership, timber trade, and diaspora history intersect. The estate remains privately managed, but the public is welcome to walk the exterior grounds, explore the woodland trails, and visit the historic cellar ruins at no cost.
A History of Oak and Aristocracy
The estate’s roots trace back to 1635, when the Wentworth family acquired the half-barony of Shillelagh. Thomas Wentworth, 1st Earl of Strafford, established a hunting lodge and park known locally as Fairwood. The stone remains of this lodge survive today as “Black Tom’s Cellar,” a name derived from Strafford’s nickname, earned from his preference for black armour and horse. After Strafford’s execution in 1641, his son William expanded the estate’s commercial focus, turning Coollattin into a major timber supplier. High-quality oak harvested here was shipped across the Irish Sea to construct Westminster Hall, Westminster Abbey, King’s College Chapel in Cambridge, and the Stadhuis in Amsterdam.
The Fitzwilliam family later inherited the estate through marriage, merging two of Ireland’s most prominent aristocratic lines. William Wentworth Fitzwilliam, 4th Earl Fitzwilliam of Ireland, commissioned the current Coollattin House – originally called Malton House – in 1794. Designed by noted architect John Carr, the neoclassical mansion was burned during the 1798 rebellion. It was rebuilt between 1800 and 1807, and by 1812 contemporary observers were praising the estate as “the best cultivated of all I have seen in Ireland.”
In recent years, the house has undergone a change of hands. Sold in 2021 to a Dublin-linked consortium, the property is now undergoing careful restoration that respects its protected status and neoclassical character. While the interior remains private, the exterior façade and formal gardens are visible from the surrounding paths, offering a striking silhouette against the canopy of mature trees.
The Irish-Canadian Famine Connection
Coollattin’s history took a sombre turn during the Great Famine. Between 1847 and 1856, approximately 6,000 tenants left the estate, many travelling to Smiths Falls, Ontario, with financial assistance from the Fitzwilliam landlords. This mass emigration created a lasting diaspora community, and in recent decades the “Coollattin Canadian Connection” has been revived to honour those journeys.
Led by local historian Kevin Lee, the project aims to formally twin the Carnew area with Smiths Falls and other Canadian towns that received these emigrants. Surnames like Byrne, Carr, Doyle, and Whelan appear on both Wicklow and Ontario gravestones, linking two continents through shared ancestry. The estate’s role as a bridge between histories was highlighted in September 2022, when the International Famine Summer School convened at Coollattin House. Scholars and diaspora participants gathered to mark the 175th anniversary of the Famine, reinforcing the site’s significance in transatlantic Irish heritage.
Walking the Woodlands & Arboretum
The estate’s arboretum is a living collection of trees, with conservation efforts actively restoring its historic oak legacy. Forestry management company Veon has overseen the planting of over 10,000 native oak saplings in the past decade, with a target of 30,000 trees across the property. The grounds now host more than 85 oak taxa, making it one of Ireland’s most diverse oak collections. Invasive species like laurel and rhododendron are systematically removed, and a 74-acre section has been designated a Seed Collection Stand for Quercus petraea and Quercus robur.
Visitors can explore several key features at a leisurely pace:
- Black Tom’s Cellar – A short walk from the main house leads to the atmospheric stone cellar of Strafford’s hunting lodge. The ruins offer a tangible link to the 17th century and make for a quiet reflection point among the trees.
- Timber Legacy Trail – Interpretive signage along marked paths explains how Coollattin’s oak supplied timber for iconic British and European buildings. Visitors can compare local wood grain with historical photographs of Westminster Hall and Amsterdam City Hall.
- Arboretum Golf Course – The 18-hole, par-72 course weaves through a living collection of native and exotic trees. The short 5th hole, tucked into a walled garden at just 120 yards, is a standout feature for golfers. Tee times are booked through the club’s portal.
- Walking & Wildlife – The surrounding woodlands support a variety of birdlife, including buzzards, woodpeckers, blackbirds, and robins. Well-maintained footpaths cater to both casual strolls and longer hikes, with occasional glimpses of the River Derry.
