This location is marked on Maps.me as a point called 'Royal Hospital Kilmainham'  This attraction refers to the house a couple of hundred metres to the east, the grounds t the location of this note and the formal gardens to the north east.

Royal Hospital Kilmainham is mapped as the entire area of the house, grounds and formal gardens, but Maps.me only displays the centroid of this as a point rather than showing the entire area as an attraction.

If this note refers to something different than this, please feel free to reactivate it and add as much information as you can about the issue.
