They will remain as full working postboxes throughout
It might look like something from the past - that's because it is.
An Post has announced plans to paint a number of postboxes in the capital red, as they appeared before independence from Britain.
In a statement, An Post says it is "bringing you closer to the streets of 1916 Dublin to witness the lesser-known stories of the Rising".
"At various locations across Dublin, painted red post boxes become beacons for the events they witnessed a hundred years ago".
The 'GPO Witness History' campaign hopes to tell the story of the Rising from the unique perspective of local, heritage postboxes that stood in silent witness to the events of the time.
They will remain as full working postboxes throughout, with regular scheduled collection and clearing.
Postboxes are to go red at several locations including Liberty Hall, the RCSI, Grafton Street, Dun Laoghaire and Northumberland Road - with more to follow.
But why these locations?
