Castle Oliver

📍 Upper Sunville, Limerick

🏛️ Attraction

Last updated: 28 April 2026

Overview

Castle Oliver, sometimes referred to as Clonodfoy, dominates the southern Limerick landscape with its red‑sandstone façade and Scottish‑Baronial silhouette. Designed by York architect George Fowler Jones between 1845 and 1850, the house was commissioned by the Oliver‑Gascoigne sisters—Mary Isabella and Elizabeth—who wanted a grand venue for entertaining rather than a fortified stronghold. The castle sits on massive terraces that overlook what was once a 20,000‑acre estate, offering sweeping vistas of the Ballyhoura mountains and the surrounding countryside.

The interior is a showcase of Victorian craftsmanship. Visitors (when the house was briefly opened for the 2014 Limerick City of Culture programme) could wander through a ballroom with a verre églomisé fireplace, a drawing‑room lined with hand‑painted ceilings, a library filled with carved wood paneling, and a series of rooms each adorned with intricate stained‑glass windows. Perhaps the most remarkable feature is Ireland’s largest wine cellar, reputed to hold around 55,000 bottles—a testament to the family’s wealth and love of hospitality.

The Oliver story begins in the mid‑17th century when Capt. Robert Oliver, a soldier in Oliver Cromwell’s army, settled the land that would later host the castle. The original Castle Oliver, located a kilometre to the south‑west, was the birthplace of Eliza Oliver, mother of the infamous Lola Montez. By the 19th century the estate had passed to the Oliver‑Gascoigne line. After marrying into the Trench family of Woodlawn, Galway, the sisters Mary Isabella and Elizabeth set about rebuilding their ancestral home.

Their choice of a Scottish‑Baronial design reflected contemporary tastes for romantic, medieval‑inspired country houses. The sisters were not merely patrons; they personally designed the stained‑glass and back‑painted glass panels that still grace the ballroom fireplace. Mary Isabella, an accomplished wood‑turner, even published an authoritative treatise on the craft under a male pseudonym. The castle remained in family hands until the late 20th century, passing through several owners, including racing driver Billy Coleman and later the Cormack family of County Antrim, who undertook extensive restoration work.

In 2015 the property was sold to the Ralph family from Australia, who use it as a seasonal home. Although the castle is a private residence and not open for regular tours, it was opened to the public from May to September 2014 as part of the Limerick City of Culture celebrations, allowing a rare glimpse inside.
