As I previously indicated in the reply to Question No. 249 of 21 June 2016, the area in question appears to be reclaimed foreshore and all of Ireland's foreshore is considered to be owned by the State, unless valid alternative title is provided.
Correspondence from Solicitors for the persons named, replying to a letter from my Department that issued in May 2016, was received on 27 March 2017. My Department will respond directly to that correspondence in the very near future again seeking details on how the area came to be reclaimed.
