I would suggest that the Glasnevin wall is fairly controversial. The one with Irish freedom fighters and UK crown forces on it. But I will try and think of it as a "British Irish" friendship monument.
Indeed, I would add that given the inevitability of the Reunited Ireland it is additionally a signal to Unionists and moreover I would suggest that in the Reunited Ireland one possibility is that we could have a National Reconciliation day for all those killed in conflict in Ireland.
Commemoration of those who laid down their lives in the struggle for Irish independence would continue as is today in a separate Commemoration as this is central to the independence we enjoy today in an independent Irish state and will continue to be so in the Reunited Ireland
