Significantly the foundations of a medieval building were identified which have been interpreted as the previously unidentified site of a gatehouse associated with the precinct of St Mary’s Abbey.
This important medieval religious institution once extended across what is now north inner-city Dublin, although there are not many surviving upstanding elements. As a result of these findings the construction design was reconfigured to facilitate preservation in-situ beneath a glass floor which will enable visibility to the public.
This approach required experienced archaeological management and continuous consultation with the statutory authorities to achieve a workable solution.
