Overview
The Corlea Trackway Visitor Centre sits on the edge of the historic boglands near the village of Keenagh in County Longford. It interprets a remarkable Iron Age road – a togher – built in 148 BC from massive oak planks. Known locally as the Danes’ Road, it is the largest prehistoric wooden causeway ever uncovered in Europe. Inside the modern interpretive building, an 18‑metre stretch of the original trackway is displayed in a climate‑controlled hall, while the surrounding peat bog offers a peaceful board‑walk and opportunities to spot bog‑cotton, dragonflies and sphagnum moss.
History
Archaeologists first stumbled upon the trackway in 1984 when workers from Bord na Móna were processing peat for a nearby power station. Radiocarbon dating placed the timbers firmly in the Iron Age, around 148‑147 BC – the same period as the Siege of Carthage. Professor Barry Raftery led the excavation, revealing a sophisticated corduroy road built from oak planks roughly 1.2 m wide, laid on parallel rails spaced about 0.5 m apart. The road stretched for at least 2 km, terminating on a small island before a second, shorter trackway continued across the bog.
Scholars debate its purpose. Some argue it was a ceremonial highway linking the ritual centre of the Hill of Uisneach with the royal site of Rathcroghan, while others suggest it allowed Iron Age peoples to enter the bog for ritual activities. Regardless of intent, the trackway was usable for only a few years before the weight of the planks caused them to sink, preserving the oak in the anaerobic peat for two millennia.
The Bog Landscape
The visitor centre sits within a carefully managed peat bog. Four artificial lakes have been created to keep the water table high, ensuring the surrounding board‑walk stays wet and the ancient timbers remain preserved. The bog supports typical flora such as bog‑cotton, sphagnum moss and a variety of dragonflies in summer. Interpretive signs explain how bogs were both practical resources and liminal spaces in ancient Irish belief.
What to See & Do
- The 18‑metre oak trackway – Walk beneath the preserved planks in a purpose‑built gallery. The oak retains its original grain, giving a tangible sense of the engineering feat undertaken over 2,000 years ago.
- Archaeological artefacts – Pottery, arrowheads, weapons and wooden containers recovered during the 1980s excavations are displayed with contextual information about Iron Age life.
- Bog board‑walk – A gently graded looped trail winds through the restored peatland, allowing visitors to experience the landscape that once concealed the road. The walk takes about 1 hour 30 minutes and offers views of the artificial lakes that maintain the bog’s humidity.
- Wildlife spotting – The bog supports a range of flora such as bog cotton and sphagnum, and insects like dragonflies are common in the summer months.
- Audio‑visual show – A short film in the visitor centre explains the excavation process and the broader significance of bog archaeology in Ireland.
- Picnic areas – Designated spots with benches let families enjoy a snack amid the tranquil scenery.
- Guided tours & school programmes – Tours are led by knowledgeable staff; groups of schoolchildren can book dedicated educational sessions that include hands‑on activities.
Nearby Walks & Trails
- Royal Canal Greenway – The canal tow‑path runs a short distance to the east and provides a flat, traffic‑free route ideal for cycling or a leisurely walk. Bicycle parking is available at the centre for those linking the two experiences.
- Corlea Bog Amenity Walk – An additional short loop that highlights the bog’s biodiversity, perfect for a quick nature escape.
- Abbeylara Cistercian Abbey – The well‑preserved medieval abbey lies about 12 km north‑west and makes a rewarding half‑day excursion.

Getting there – The centre lies about 3 km north‑west of Keenagh on the R357. From Ballymahon, follow the R392 north‑west; the site is sign‑posted. It is also reachable from Longford town (≈15 km) via the R392. Public transport is limited, so a car is the most convenient way to visit. A local bus runs from Longford to Keenagh; the stop is a short walk from the centre.
Facilities – Restrooms, a wheelchair‑accessible toilet, a small café serving hot drinks, and a picnic area are on site. Bicycle parking is provided for those cycling the Royal Canal Greenway before or after their visit.
Seasonal note – The bog walk remains open only while the bog is kept wet for conservation; the centre closes for the winter months (mid‑November to mid‑March). Check the official website for any temporary closures.
