It’s little wonder that half the country is flooded. Over the years, the OPW has done superb work, in terms of restoring or protecting our built heritage. Newgrange, Dublin Castle and the Oldbridge Estate are three splendid examples. In total, the OPW has responsibility for 780 heritage sites or buildings, which is no mean task. But it is also responsible for flood risk management, an area in which their brilliance is assuredly more uncertain.
