It should be noted that the issues raised by the Deputy are not areas which are directly my Department's area of responsibility. As the Deputy may be aware, however, I understand there has been some debate on the question of the original location of 9th century Viking Dublin settlements. This aspect would in the first instance be of academic or of professional interest. I do not, therefore, consider it appropriate to offer a comment on such an issue.
However, I wish to advise the Deputy that, as he may be aware, the extensive excavations carried out by the National Museum of Ireland have revealed much on the archaeology of Viking and medieval Dublin from the 10th century.
