The dataset is held by and hosted by Department of Housing, Local Government and Heritage. The Zone of Archaeological Potential (CO074-034--001) for the City Centre includes the medieval historic core. There are 54 RMP sites located within this Zone and these include the site of the original monastery of Saint Fin Barre and the medieval walled defences. In the medieval historic core archaeological remains lie within a metre of the modern surface, particularly in the North and South Main Street area and these strata can be present to a depth of 3 to 4m in places. Outside the historic core, the Zone of Archaeological Potential covers the un-walled medieval suburbs, known sites of medieval religious houses (Red Abbey), and parts of the city which were developed in the seventeenth and eighteenth centuries when marshes were reclaimed and new streets laid out.
