Overview
Kilfane Glen sits in a 6-hectare valley on the edge of the Kilfane demesne, just outside Thomastown in County Kilkenny. Laid out in the 1790s by Sir John and Lady Power, the grounds blend formal 18th-century planting with the rugged, naturalistic style of the Romantic movement. A 30-foot waterfall drops into a clear pool, surrounded by mature beech, chestnut and oak. At its base stands a thatched cottage-or-né, originally built as a summerhouse for entertaining guests. The adjacent Kilfane House, a Georgian mansion, overlooks the garden and the ruins of a 13th-century church. Recognised as an Irish Heritage Garden, the site remains one of the southeast’s most intact examples of early landscape design.
History & Landscape
The Power family, prominent cultural patrons in the region, commissioned the garden’s transformation in the 1790s. They diverted a local stream, dug a mile-long feeder canal and engineered the dramatic cascade that still anchors the glen. Their design drew heavily on Enlightenment thinkers like Rousseau, favouring winding paths, stone bridges, a rustic grotto and carefully placed follies over rigid symmetry. Contemporary visitors, including Louisa Beaufort in 1819, noted the garden’s striking atmosphere.
By the late 19th century, declining family fortunes led to neglect. Paths became overgrown, the watercourse ran dry and the thatched summerhouse deteriorated. Because the estate sat on the fringes of later farming expansion, the garden escaped the clearance that destroyed many similar demesnes. Surviving sketches and watercolours guided a careful early-21st-century restoration led by the Kilfane Trust. Today, the original layout is complemented by seasonal site-specific sculptures that create a quiet dialogue between historic horticulture and contemporary art.
Kilfane House stood empty for decades before the Seraph Foundation acquired the protected building in 2019. As of March 2026, planning applications are underway to convert the mansion into a holistic healing retreat, incorporating guest rooms, event spaces and sustainable energy systems.
What to See & Do
- Woodland & Formal Gardens – The route moves from manicured lawns into shaded trails. Spring brings carpets of bluebells, while ferns and mosses thrive year-round. Look for the original stone bridges, weathered boulders and the historic grotto tucked into the rock face.
- The Waterfall – The engineered cascade drops 30 feet over natural rock. Flow varies with the seasons, shifting from a steady winter rush to a lighter summer trickle. The pool below is a popular spot for quiet reflection or a packed lunch.
- Thatched Summerhouse – Positioned at the foot of the falls, the cottage-or-né remains intact. It is open for viewing from the garden paths and makes a striking photograph, though the interior is not accessible to the public.
- Kilfane House & Church Ruins – The Georgian mansion frames the upper garden. From designated viewpoints, you can also see the remains of Kilfane Church, dating to the 13th century, which historically housed a notable Norman knight effigy.
- Contemporary Installations – The Trust commissions rotating works by Irish and international artists. Pieces are placed throughout the upper garden to engage with the existing topography and planting.
Practical Information & Visitor Tips
- Getting There – Access the estate via the R704 from Thomastown. A small, free car park sits at the entrance. On summer weekends it fills quickly, so aim for early morning or late afternoon arrivals.
- Public Transport & Cycling – Bus Éireann services run regularly from Kilkenny City and Waterford to Thomastown. From the town centre, the glen is a 2 km walk or a short taxi ride. The surrounding lanes are quiet and popular with cyclists; bike racks are available near the visitor entrance.
- Admission & Payment – Entry costs €7 per adult. The site operates on a cash-only basis, so bring appropriate change or notes. Concessions apply for families, seniors, students and pre-booked groups.
- Facilities & Accessibility – Toilets are located at the glen entrance. Picnic tables are positioned near the waterfall. Paths are primarily gravel and can be uneven or slippery after rain; sturdy footwear is recommended. The site is best suited to visitors comfortable with moderate walking.
- Dogs – Leashed dogs are welcome in the outer woodland trails but must be kept out of the formal garden sections to protect the historic planting.
