📍 Portroe, Tipperary

🏛️ Attraction

Last updated: 28 April 2026

Overview

Portroe (Irish: Port Ró) is a picturesque village set on the R494 regional road, only 2 km from the eastern shore of Lough Derg and 11 km west of Nenagh. With a 2022 population of 459, the settlement spreads across the townlands of Garrykennedy, Glencrue and Shesharoe. The village is a hub for local sport, music and community events, and it offers easy access to the stunning natural scenery of the Arra hills and the sparkling waters of Lough Derg.

History

Evidence of ancient habitation surrounds Portroe: standing stones, rock‑art panels, a ring‑fort and the ruins of a tower house dot the nearby townlands of Garrykennedy, Lisheenbrien and Lisheentyrone. The village’s Roman Catholic church, dedicated to St Mary, dates from 1872, while a former Royal Irish Constabulary barracks, built around 1830, crowns the hilltop at the village’s edge. On Loughtea Hill, one of the Arra hills southwest of Portroe, a 20‑metre stainless‑steel cross was erected in 2002 to mark the millennium, replacing an earlier cross from the 1932 Eucharistic Congress.

What to See & Do

Village Highlights

  • St Mary’s Church – a modest 19th‑century stone church that sits at the heart of village life.
  • Historic RIC Barracks – a rare surviving example of early‑19th‑century law‑enforcement architecture, now a visual landmark.
  • Loughtea Hill Cross – climb the hill for panoramic views over Lough Derg and the surrounding countryside; the cross glints in the sunlight, especially at sunrise.
  • Community Hall & Handball Alley – the hall hosts classes, local GAA meetings and cultural events such as Scór, while the old handball alley offers a glimpse of traditional Irish sport.
  • Portroe GAA Club – catch a hurling or camogie match in the summer months; the club produced Liam Sheedy, former Tipperary manager.

Portroe Quarry – The Blue Lagoon

Portroe Quarry, perched above the village, is a disused slate quarry flooded by a freshwater spring. Since 2010 it has operated as Ireland’s first inland dive centre, offering crystal‑clear water that can reach depths of 40 m. Divers can explore:

  • Two car wrecks at ~12 m, an underwater “pub” installed by the dive centre, and a sunken boat frequented by eels.
  • Remnants of the quarry’s industrial past – an old mining shaft, iron ladder and a crane at 27 m.
  • For non‑divers, the original entry ramp and slipway provide a striking photo‑op where the blue water seems to vanish into the horizon.

Nearby Attractions

  • Garrykennedy – a short five‑minute drive brings you to this Lough Derg lakeside village, where the restaurant Larkins serves hearty Irish fare and live music.
  • Killaloe & Ballina – fifteen minutes away, these twin towns on the River Shannon offer historic streets, craft shops and riverside walks.
  • Arra Hills – gentle hillwalking routes provide sweeping vistas of the lake and countryside.
  • Ardfinnan – a nearby village with a medieval bridge and castle ruins, ideal for a quick detour.

Events & Festivals

  • Annual Vintage Day – organised by the Portroe Tidy Towns Committee each August, this family‑friendly event showcases classic cars, vintage stalls, live music and local food vendors.
  • GAA Summer Fixtures – Portroe GAA Club hosts regular hurling and camogie matches from May to September; match days are a lively way to experience community spirit.
  • Scór & Music Sessions – the community hall runs seasonal traditional music sessions and Scór competitions, often open to visitors.
