Excavations



Introduction to the work
Archaeological excavations have been on-going by Archaeological Development Services Ltd within Bord na Móna peat bogs in Counties Offaly and Longford. Bord na Móna has supported and funded this series of excavations as part of the Principles and Agreements reached between the Department of Arts, Heritage, Gaeltacht and the Islands, The National Museum, Bord na Móna and the Department of Public Enterprise where it was agreed that an appropriate level of professional excavation of archaeological sites and objects will be undertaken on milled peat bogs. This project began over two years ago and since then over 60 separate excavations have taken place. In conjunction with these excavations some of the previously identified wooden archaeological sites have been set aside in areas which will not be milled thereby leaving some of the archaeological sites and artefacts for future generations to study. These excavations and associated research will continue over the next few years and will be carried out on previously recorded sites in Bord na Móna bogs.

Site and artefacts
The wealth and diverse nature of archaeological sites and artefacts that are preserved in our peatbogs is unparalleled elsewhere. These archaeological sites and artefacts are being exposed on the bog surface during the Bord na Móna peat production process. Archaeologists carry out excavations and interpret these sites in advance of further peat harvesting. These excavations coupled with the discovery of artefacts by workers in Bord na Móna bogs, create a better understanding of the local heritage of a specific area. Small glimpses of the peoples who constructed these sites can also be seen through some of the artefacts unearthed during these excavations.

A wide range of archaeological sites and artefacts survive within and under Irish peatlands. The trackway or togher, as it is commonly called, is the most frequent class of site encountered. These aided the safe crossing of an otherwise treacherous bog. They were constructed using a variety of materials such as oak planks, hazel/alder/birch/willow rods, gravel or flagstones and were in use from over 5000 years ago up to relatively recent times.

It is clear that bogs were not only seen as obstacles to cross but their natural flora and fauna were almost certainly exploited particularly in the Medieval period. Increasing evidence for this comes in the form of small wooden platforms, possible hunting blinds, which were constructed, in the raised bogs. Download PDF of Excavations in Corhill Bog, Lisdermot.

Farming reached Ireland in the Neolitic period around 3500 BC and with it came forest clearance, cereal crops, large stone monuments dedicated to the dead and a specialisation in the production of tools such as stone axe heads. A polished stone axehead of fine green-grey stone, assigned to this phase, was unearthered by Joe Egan, a BnM worker, at the north west end of the Lemanaghan bogs. Close by, in the same bog, a hollow flint scraper was uncovered during survey work carried out by the Irish Archaeological Wetland Unit in Corhill bog, Co. Offaly. Further milling and excavations in the lower peat levels of the bogs is likely to uncover more early stone age artefacts and associated archaeological trackways and sites.
