National Roads Authority (NRA)

Archaeological Geophysical Survey Database

The Geophysical Survey Database contains an archive of archaeological geophysical survey reports carried out for the National Roads Authority in advance of new road schemes in the Republic of Ireland between 2001-2010.

The geophysical surveys were commissioned by the NRA to prospect for previously unknown archaeological sites and/or to investigate known or suspected archaeological sites along several km of road. The geophysical surveys were carried out by a number of geophysical consultancies from Ireland and the UK, resulting in more than 170 individual reports.

Each report has been archived as part of a Research Fellowship carried out by the University of Bradford in partnership with Earthsound Archaeological Geophysics. The NRA archive represents more than 1,700 hectares of archaeological geophysical investigation, spread across the country.

Report Format: The reports are available as .pdf documents and can be downloaded freely by the public. Each report contains an inventory sheet with basic information about the survey, road scheme, location and directions for researchers on how to acknowledge and reference the work of the geophysical consultant. Some of the reports may have incomplete elements that could not be archived and these are noted in a red outlined box on the inventory sheet.

Acknowledgement: The NRA and the University of Bradford would like to thank all the geophysical consultants that worked on Irish road schemes between 2001-2010, culminating in this archive.
