Overview
Castlestrange House sits on the banks of the River Suck, a short drive north‑west of Athleague in County Roscommon. The three‑storey country house, erected in the early 19th century, now stands as a striking ruin surrounded by a coach house, stables and a gate lodge. Within the demesne’s driveway rests the Castlestrange Stone – a granite boulder incised with classic La Tène spirals dating from c. 300 BC to 100 AD. The stone is a protected National Monument and one of only four such Celtic cult stones recorded in Ireland.
History / Background
- Medieval origins – The estate originally hosted a medieval castle built by the L’Estrange family.
- 18th‑century transition – The Mitchell family acquired the land in the early 1700s and replaced the castle with a more genteel residence.
- 19th‑century house – By the 1830s the present three‑storey house was completed, featuring an L‑plan layout, slate roof and a pedimented bellcote.
- Veterinary milestone – In the 1890s surgeon Willie Byrne opened a veterinary practice on the grounds. It was here that Aleen Isabel Cust, Ireland’s first female veterinary surgeon, began her career, adding a notable social footnote to the estate.
- 20th‑century decline – After Byrne’s death (1910) the property changed hands, being sold to William J. Finerty in 1915. The Finerty family occupied the house until the mid‑20th century, after which the main building fell into abandonment. The outbuildings have since been repurposed as private dwellings, while the house itself remains a derelict shell overgrown with ivy.
- The La Tène stone – Likely introduced to the landscape as a decorative feature, the stone measures roughly 60 cm high and 90 cm long. Its incised spirals are characteristic of the Celtic La Tène artistic tradition that flourished across Iron Age Europe. Together with the Turoe Stone (Co. Galway), the Killycluggin Stone (Co. Cavan) and the Derrykeighan Stone (Co. Antrim), it forms a line of four monuments that has intrigued archaeologists for decades.
What to See & Do
- Explore the ruined house – Walk around the remaining walls to appreciate the original L‑plan layout, the slate‑roofed roofline, and the family crest set into the coach house wall. The pedimented bellcote and ivy‑clad windows create a hauntingly beautiful tableau.
- Examine the Castlestrange Stone – Circle the boulder and study the better‑preserved side where the incised spirals pulse with ancient energy. The stone’s flowing arcs offer a tangible link to Iron Age ritual practice.
- Compare with the other La Tène stones – If time allows, organise a day‑trip to the Turoe Stone in Galway, the Killycluggin Stone in Cavan, or the Derrykeighan Stone in Antrim to see stylistic variations across the island’s Celtic monuments.
- Enjoy the surrounding landscape – The estate’s gardens and the gentle fields of Roscommon provide peaceful backdrops for photography, picnics and quiet contemplation. On clear days the River Suck glints in the distance.
Nearby attractions
A short drive north‑east brings you to Boyle Abbey, a well‑preserved Cistercian ruin set on the banks of the River Boyle. Combining a visit to Castlestrange House with Boyle Abbey makes for a rewarding half‑day itinerary that showcases both medieval monastic architecture and later Georgian‑era country life. For those interested in further historic houses, the Georgian mansion at Castlecoote lies a few kilometres south‑west and is open to the public during the summer months.
