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.

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

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.
