I propose to take Questions Nos. 155 and 156 together.
The term "medieval" is now generally understood to mean the period from the mid-fifth century AD to the mid-sixteenth century AD. It is not possible at this time to estimate the total number of known archaeological monuments and sites of all categories falling within that period in the records of the Archaeological Survey of Ireland. However, it would be a substantial percentage of the approximately 120,000 monuments and sites entered in the record of monuments and places established under section 12 of the National Monuments (Amendment) Act 1994. All such sites are protected under the National Monuments Acts 1930-1994.
The archaeological excavation of medieval sites, other than in mitigation of development impacts, is carried out under either programmes of conservation works at monuments or research projects. To date an estimated 250 archaeological excavations have been carried out on this basis by my Department and its predecessors or by other authorised archaeological teams at medieval sites of all categories. Similar excavations in the future will take place in accordance with the deployment of proposed conservation or research projects.
