A blue plaque has been installed at Ebrington in Londonderry in honour of the poet Francis Ledwidge.
He wrote some of his finest works while stationed at the barracks, before the Battle of Passchendaele erupted in Belgium one hundred years ago.
Ledwidge was one of more than half a million casualties of the battle.
The blue plaque commemorating his life overlooks the parade ground he knew so well, when he was based at Ebrington with the Royal Inniskilling Fusiliers.
He was from Co Meath, but this was military home. His great-nieces were among those who attended the ceremony.
Eileen Ledwidge-Wilson said: "We've always been brought up with the history of uncle Frank and the love of Ireland."
At the outbreak of the Great War, Ledwidge wrote that he looked forward to poetry and fame after the war - but it would never be.
A hundred years ago this week, Lance Corporal Francis Ledwidge died in the mud and the blood of Passchendaele.
He was just days short of his 30th birthday.
In recent days the centenary of Passchendaele has been marked by a memorial event at the Menin Gate in Belgium.
A Ledwidge poem was read out at the ceremony, with the soldier poet - like the guns on the Western Front - echoing down through the years.
