Construction and suggested purpose
Souterrains are underground galleries and, in their early stages, were always associated with a settlement. The galleries were dug out and then lined with stone slabs or wood before being reburied. In cases where they were cut into rock this was not always necessary. They do not appear to have been used for burial or ritual purposes and it has been suggested that they were food stores or hiding places during times of strife, although some of them would have had very obvious entrances.

. It was in total length and was constructed in a 'C' shape with two distinct chambers. A linear ditch was located immediately adjacent to the souterrain and was connected to the southwest chamber by a tunnel. This tunnel sloped gently downwards towards the chamber and its edges were iron-panned, indicating that water had run through it for a significant amount of time. This indicates the southwest chamber was used as some kind of water collection and storage system. The soil into which the souterrain was dug was soft sand that would have been impossible to maintain without a lining; the presence of stake holes along the edge of the northeast chamber and the lack of stones means that the walls would have been wood-lined. Radiocarbon dating suggests occupation between the 1st and 3rd centuries AD.

. The distribution of souterrains is very uneven in Ireland, with the greatest concentrations occurring in north Louth, north Antrim, south Galway, and west Cork and Kerry. Lesser numbers are found in counties Meath, Westmeath, Mayo, north Donegal, and Waterford. Other counties, such as Limerick, Carlow, and Wexford, are almost completely lacking in examples.
[Clinton, M. (2001). ''The Souterrains of Ireland'', p. 33. Wordwell, Bray.]
An article by Warner on the archaeology of souterrains, although published years ago, still is possibly the best general overview of the subject.
The most comprehensive study of Irish souterrains is M. Clinton's 2001 work, containing chapters on distribution, associated settlements, function, finds, chronology and 13 appendices on various structural aspects of souterrains.
A short summary account of souterrains in Ireland appeared in the quarterly magazine ''Archaeology Ireland'' in 2004.
