Overview
Glinsk Castle is one of the last true tower houses built in Ireland. It went up in the early 1600s, just as landowners were giving up fortified homes for comfortable unfortified ones, and it barely got the chance to grow old: the Cromwellians gutted it by fire within a few decades. The roofless shell still stands over the fields, and its run of tall chimney stacks is the reason to come.
The castle sits by the small farming village of Glinsk (Irish: Gleann Uisce, ‘glen of the water’), near the Galway–Roscommon border between Creggs and Ballymoe, in the valley of the River Suck. It’s out of the way – roughly 68 km from Galway city and 30 km from Roscommon town – with little tourism machinery around it. That’s rather the appeal, but plan for it: no café, no toilets, and a gate that is sometimes locked.
Glinsk Castle
The castle was the seat of the Burke (de Burgo) baronets, an Anglo-Norman family with long reach across Connacht; it’s usually credited to Ulick Burke and dated to the early seventeenth century. What survives is a rectangular block with two projecting towers on the south side, and the detailing is unusually complete for a ruin: five-shafted chimney stacks, mullioned windows with weeper dripstones, defensive gun loops, and a three-centred pointed arch over the south door. Corbelled bartizans still cling to the tower corners. West of the main ruin you can trace a stretch of the bawn wall and the footing of a circular turret, enough to read the old defensive line.
The chimney stacks are what people photograph, and rightly – there’s little else like them left standing in Ireland. From the upper windows the ground opens out across the so-called Glen of Glinsk, and on a clear day local lore has it you can pick out five counties of Connacht.
Ballinakill Abbey
A short way off stand the ruins of Ballinakill Abbey, a church site going back to the early thirteenth century. Its best-known feature is a carved Burke effigy, a reminder that the same family shaped the religious landscape here as well as the military one. Together with the castle it makes Glinsk a compact stop for anyone interested in the Burkes and medieval Connacht.
The village and the Suck Valley Way
Glinsk is a living place, not just a ruin: it has St Michael’s church, a shop, a pub, a GAA pitch, a primary school and a community centre. The local development group completed a heritage audit of the area in 2025 and runs events through the year, from the Great Glinsk Run to a Christmas fair, so there’s more going on than the quiet lanes suggest.
Walkers can pick up the Suck Valley Way, a roughly 60-mile (97 km) waymarked trail that follows the River Suck through the lowlands of Roscommon and Galway, past riverbanks, ringforts and old churches. Glinsk makes a reasonable access point for a shorter section rather than the whole thing.
Getting there and practical information
Glinsk lies off the main Galway–Roscommon road near the county border; signage points you into the village, where a small car park sits within walking distance of the castle. Public transport is minimal – the nearest regular buses run from larger towns some distance away, so a car is effectively necessary.
- Access and opening: The site is open year-round with no admission charge and no fixed hours; the castle is accessible at any time. If the entrance gate is locked, a key is kept at a house near the castle.
- Parking: Free in the village car park, but spaces are few, so come early on summer weekends.
- Facilities: None on site: no visitor centre, café or toilets. Bring water and weather-appropriate clothing.
- Footwear and safety: The castle is roofless and the ground uneven, with loose limestone and worn steps. Wear sturdy boots and take care near the high basements and the bawn remnants, especially after rain.
You don’t need a full day. Allow an hour or two, and if the gate’s locked, ask at the nearest house for the key rather than turning back – the chimney stacks are worth the small effort.
