Overview

Roscommon Castle, Co. Roscommon
Roscommon Castle, Co. Roscommon Tourism Ireland

Nestled on the banks of the River Suck, a short drive north‑west of Athleague in County Roscommon, lie the evocative ruins of Castlestrange House and the striking Castlestrange Stone. The three‑storey early‑19th‑century house now stands as a skeletal reminder of the estate’s former grandeur, while the granite boulder set in its driveway bears incised La Tène spirals dating from c. 300 BC to 100 AD. Both features are listed as a National Monument, offering a rare blend of architectural decay and Iron Age artistry in a peaceful rural setting.

History / Background

The site originally hosted a medieval castle built by the L’Estrange family. In the early 1700s the Mitchell family acquired the land and replaced the stronghold with a genteel residence, culminating in the three‑storey house completed in the 1830s. Outbuildings – a U‑plan coach house, stables and a gate lodge – survive as private dwellings.

In the 1890s the estate became a veterinary practice run by surgeon Willie Byrne, where Aleen Isabel Cust, Ireland’s first female veterinary surgeon, began her career. After Byrne’s death the property passed to William J. Finerty in 1915; the Finerty family occupied the house until the mid‑20th century, when the main building fell into abandonment and was overtaken by ivy.

The Castlestrange Stone, measuring roughly 60 cm high by 90 cm long, was likely relocated to the demesne as a decorative landscape feature. Its incised spirals are characteristic of La Tène art, linking it to the only four such stones recorded in Ireland – the Turoe Stone (Co. Galway), the Killycluggin Stone (Co. Cavan) and the Derrykeighan Stone (Co. Antrim). Unlike the raised‑relief carvings of the Turoe Stone, the Castlestrange Stone’s lines are cut into the granite, a technique that gives the motifs a subtle, flowing quality.

What to See & Do

  • Explore the ruined house – Walk the perimeter to view the remaining L‑plan walls, the pedimented bellcote and the family crest set into the coach house. The roofline still hints at the original slate covering. For more detail on the house see the dedicated page on Castlestrange House.
  • Examine the La Tène stone – Circle the stone and study the better‑preserved side where the spirals pulse with ancient energy. The incised design creates a sense of movement that feels almost shamanic.
  • Compare the four Irish La Tène stones – A day‑trip to the nearby Turoe Stone (County Galway) or the Killycluggin Stone (County Cavan) highlights stylistic variations across the island’s Celtic network.
  • Enjoy the landscape – The estate’s gardens and surrounding fields provide gentle views of rolling Roscommon countryside, occasional glimpses of the River Suck, and ample opportunities for photography and quiet contemplation.

Seasonal Highlights

April 18th marks International Day for Monuments & Sites. Across Ireland, heritage organisations encourage visitors to learn about and protect archaeological sites. While Castlestrange is not the focus of a specific event, the day offers an excellent opportunity to visit the ruins and reflect on the importance of safeguarding such National Monuments. The Office of Public Works and the National Monuments Service promote the “Code for Caring for our Monuments” guidance during this period, outlining how visitors can help protect fragile sites.

Conservation and Visitor Guidance

Castlestrange House and its stone are protected under the National Monuments Service. The Office of Public Works (OPW) advises visitors to:

  • Stay on the designated footpaths and avoid touching or moving any stones.
  • Refrain from digging, climbing on unstable walls, or disturbing vegetation.
  • Report any damage or vandalism to Roscommon County Council.

These guidelines help preserve the delicate La Tène carvings and the fragile masonry of the house for future generations.

Heritage Guidance

The OPW’s “Code for Caring for our Monuments” (published in conjunction with the International Day for Monuments & Sites) provides practical tips for visitors to historic sites across Ireland. Key points relevant to Castlestrange include:

  • Do photograph the stone and ruins from a respectful distance.
  • Don’t lean on the remaining walls or attempt to climb the bellcote.
  • Do keep dogs on a short leash and under control, as the site lies on private land.
  • Don’t remove any loose stones or artefacts; even small fragments can be archaeologically significant.

Following these simple actions ensures that the site remains intact for future generations and respects the rights of the private landowners.

Getting There

  • By car: The site is accessed via the R368 road, with a small lay‑by just off the main drive. Signage for Castlestrange House is limited, so a GPS coordinate (53.58685 N, ‑8.27183 W) is useful.
  • Public transport: Bus services to Athleague are infrequent; a private vehicle or taxi is the most reliable way to reach the ruins.
  • Parking: There is a modest on‑site car park beside the house. Visitors should park responsibly and avoid blocking the private driveway.

Nearby Attractions

  • Athleague Village and Castle – A short walk north of the ruins, the historic village offers a small heritage centre and a medieval tower house.
  • Castlecoote – A well‑preserved 17‑th‑century manor set in beautiful gardens, located about 10 km east of Castlestrange.
  • Boyle Abbey – The impressive Cistercian ruin lies roughly 20 km south‑west and makes an excellent addition to a Roscommon heritage day‑trip.

Practical Information

  • Opening hours: No formal hours or admission fee; the site is freely viewable during daylight.
  • Access: The stone and house sit on the private grounds of Castlestrange House. Visitors are asked to stay on the designated footpaths and respect the property.
  • Location & Coordinates: 53.58685 N, ‑8.27183 W (approximately 5 km north‑west of Athleague, County Roscommon).
  • Transport: Reachable by car via the R368 road; there is limited public transport, so a private vehicle is recommended.
  • Facilities: No visitor centre or amenities on site. Nearby towns such as Athleague and Roscommon town provide cafés, restrooms and parking.
