Bog of Allen

The Bog of Allen (Móin Alúine in Irish) is a large raised bog in the centre of Ireland between the rivers Liffey and Shannon.

The bog's 958 square kilometers (370 square miles) stretch into County Offaly, County Meath, County Kildare, County Laois, and County Westmeath. Peat is mechanically harvested on a large scale by Bórd na Móna, the government-owned peat production industry. The area has miles of narrow gauge industrial railways for transporting turf to processing plants and turf powered power plants. In addition, the cutover portions are used as area for grazing. The bog is crossed by the Grand Canal and the Royal Canal.

The Irish Peatland Conservation Council describes the bog as "an important area of peatland, as much a part of Irish natural heritage as the Book of Kells." The bog is much reduced after centuries of agricultural exploitation and recent encroachments by development. Efforts are underway to preserve sections of it.

The peatlands of the Bog of Allen contain a valuable part of the archaeological record. Due to the special preservation conditions within peat, many kinds of artefact which do not normally survive are preserved; these include for instance wooden structures and objects. In many parts of the Bog of Allen industrial milling has uncovered archaeological remains such as trackways. These trackways are wooden walkways constructed through prehistory and into the medieval period which allowed people and animals to cross the extensive areas of peatland, which can give us an insight into the economy and way of life of the societies that existed around the bog. The preservation conditions in bogs also preserve a range of palaeoenvironmental evidence such as pollen and plant macrofossils which are often studied alongside the archaeological evidence to inform about the environment on and around the bog.
