An Post have paid tribute to the 40 children killed around the GPO during the Easter Rising by placing a new memorial in its courtyard.
The emotive monument, which consists of 40 stones - each symbolising a lost life - is part of An Post's new €10m Witness History centre, an interactive museum focusing on Easter 1916.
The centre tells the story of the children who died - and even contains some of their historical artefacts.
RTE broadcaster Joe Duffy has been key in highlighting the story of the children that died, many of whom had almost been forgotten in the history books. He was particularly happy that they now have a memorial of their own.
"Put it this way, it takes less than 40 seconds to read out those 40 names, but it has taken 100 years for them to be commemorated," Mr Duffy told the Herald.
"I think the seven signatories of the proclamation would have wanted it."
Mr Duffy commended An Post for the fabulous work they have done on the centre.
The monument has been placed in the newly-restored inner courtyard of the GPO and was designed by artist Barbara Knezevic.
Ms Knezevic used stones from the foundations of the Jacobs biscuit factory in Dublin, which was occupied by volunteers during the rising.
The centrepiece of the new attraction, which will be opened officially on March 25 by Enda Kenny, is a giant, semi-circular cinema screen which provides spectators with an audio visual journey through Easter 1916.
Actors in Irish Volunteer and Cumann na mBan uniform have been employed to guide visitors through the interactive centre, which includes artefacts from the era.
