The Archive Unit

The Archive Unit is a section within the National Monuments Service, Department of Culture, Heritage and Gaeltacht and consists of an extensive body of material relating to the archaeological heritage of the State.

The main collections consist of the Record of Monuments and Places (RMP) files comprising reports on some 136,800 archaeological sites within the State; c.25,000 excavation reports on the results of licensed and unlicensed excavations; a Carved Stone Inventory collection; underwater survey volumes, including the Shipwreck Inventory and Ports, Piers and Harbours volumes; and an extensive photographic collection of some 550,000 images of monuments. The Archive Unit is also in the process of providing storage for the transfer of paper archives from excavations carried out under licence.
