A delegation from the European Parliament's Petitions Committee is visiting the medieval Carrickmines Castle site in south Dublin today.
The site is at the centre of a row over its conservation and has led to a delay in the completion of the M50 motorway.
Labour MEP for Dublin, Proinsias De Rossa, and the Friends of the Irish Environment group are alleging that €75 million of EU road-building funds are being inappropriately spent because of an inadequate Environmental Impact Statement for the M50.
Dun Laoghaire-Rathdown Council vigorously disputes this, saying it has always abided by the law and has made every effort to accommodate concerns while achieving the long-awaited goal of finishing Dublin's ring-road.
The committee ìs visiting the ruins of the Carrickmines Castle today and will raise any concerns with the Minister for Transport, Séamus Brennan tomorrow.
The delegation, led by Mr De Rossa, will include Felipe Camison, MEP Christian Democrats, Spain; Margot Kessler, MEP Socialist Party, Germany; and David Lowe, Official from the European Parliament Petitions Committee.
They will be joined by medieval historians Dr Seán Duffy, Trinity College and Kenneth Nichols of University College Cork. Both want to keep the entire site intact.
The issue is currently before the High Court.
