The Galway Archaeological and Historical Society was founded on the 21 March 1900, at the Railway Hotel, Galway. It promotes the study of the archaeology and history of the west of Ireland. Since 1900, the Society has published 60 volumes of the Journal of the Galway Archaeological and Historical Society. The first 55 volumes of this journal are available for purchase on CD-ROM.
The Society also runs a lecture series in Galway City, as well as outings to various sites of interest during the summer. It is also involved in lobbying national and local authorities in relation to heritage matters relating to the City and County of Galway.
