Overview
In 148 BC, someone laid a road of oak planks across a bog outside Keenagh. It ran for over two kilometres, and within a few years the weight of the timber pushed it under the peat, where the airless bog kept it almost intact for two thousand years. That road, the Corlea Trackway, is the reason people drive to this corner of County Longford, and it’s the main thing to see.
Keenagh itself (Irish: Caonach, meaning ‘moss place’) sits just south of Longford town on the R397, beside the Royal Canal. It’s a working village of two churches, three pubs, a couple of shops and active GAA and soccer clubs, with a population of 581 at the 2016 census. Longer roots show in its links to the King-Harman family and the old Mosstown Estate, and in a rare single-storey thatched building on the street, the last survivor of a former terrace.
The Corlea Trackway
The trackway, known locally as the Danes’ Road, is a togher, an Iron Age road built from split oak planks laid across parallel runners. At over two kilometres it is the largest prehistoric bog road uncovered anywhere in Europe. Historians read it as part of a routeway of real importance, possibly a ceremonial road linking the Hill of Uisneach, the ritual centre of Ireland, with the royal site of Rathcroghan.
It was also, in engineering terms, a near-instant failure. The oak was too heavy for the soft peat and the road sank within years of being finished, unusable almost as soon as it was built. That failure is why it survived: sealed in anaerobic bog, the timber was preserved until Bord na Móna peat workers hit it in 1984. The excavation that followed, led by Professor Barry Raftery in 1991, recovered the corduroy road along with wooden tubs and pottery.
The visitor centre and bog walk
Heritage Ireland’s centre keeps an 18-metre length of the original oak indoors, in a climate-controlled hall you walk beneath on a short guided tour, with the recovered artefacts and displays on bog ecology alongside. The preserved timber is the reason to come, and access to that gallery is by the guided tour, so check in at reception when you arrive.
Outside, a level 2 km loop runs through restored raised bog, laid out with model planks marking the line of the original road. It’s step-free and gently graded, and takes an hour or so at a walk. Look for bog cotton, sphagnum, sundew and bog rosemary, with dragonflies in summer and the odd curlew or hen harrier overhead. Benches along the way make it an easy amble rather than a hike.
Around the village
The two parishes and the three pubs are the village’s fixed points, with trad sessions and locally sourced food in the bars and a community centre that keeps the place ticking year-round. The Royal Canal towpath runs close by, flat walking and cycling in either direction, and the restored 40th and 41st Locks, at Mullawornia and Coolnahinch Bridge, still carry their original timber gates and accommodation bridges.

Nearby
Keenagh works as a base for the wider county:
- Abbeylara – Ruins of a medieval Cistercian abbey among walking routes.
- Aughnacliffe – A well-preserved dolmen and lakeside trails, about 35 km north.
- Ballinalee – A historic village with heritage sites and nature walks.
- Clonbroney – Early monastic remains in a quiet rural setting.
- Lanesborough – A Shannon-side town for boating and dining.
Allow about 90 minutes for the gallery, the audio-visual and the bog loop, and check the Heritage Ireland site before you travel, both for the seasonal dates and for guided-tour times.
