The ideal situation is that only researched excavation should take place. In reality, if development of the medieval city is to take place, interference with its archaelogical remains is inevitable. In this connection, the National Monuments Advisory Committee recommended in its urban archaeology guidelines that development should have minimal interference with archaeological layers, thereby conserving archaelogical deposits for future discovery and examination.
A large number of excavations have taken place over the past 20 to 30 years and the results of these have not yet been fully assimilated. Any future research should take account of knowledge obtained from earlier excavations — not only in terms of findings but in terms of methodology. Large scale archaeological research is now a matter for the discovery programme, which has identified the late bronze age and early iron age as the priority areas for study. No doubt in due course, they will turn their attention to medieval Dublin to work on the preserved archaeological deposits.
