A new museum is to be established to tell the story of Irish soldiers in the British Army down the centuries.
The £13.6 million (€16.3m) project will be developed across two sites in Northern Ireland, in Belfast and in Enniskillen, Co Fermanagh.
The Belfast gallery is a new development and is set to open in 2027.
The museum will tell the stories of men like Private James Duffy from Gaoth Dobhair in Co Donegal who won a Victoria Cross for his bravery as a stretcher bearer during the First World War.
During the 19th Century around 40% of the British Army was made up of soldiers from across the island of Ireland.
Their role in World War One is well known, but they also played a significant role at the Battle of Waterloo in 1815, where Corporal James Graham from Co Monaghan was described by the victorious Duke of Wellington as the "bravest man at Waterloo".
The new Belfast gallery will open in a restored linen warehouse in Bedford Street, close to the city hall.
An existing exhibition at Enniskillen Castle will also be refurbished.
They will draw together exhibits and information from six collections under the banner "UNTOLD - Stories of the Irish in the British Army".
Dr Laura Patrick, project director said the new exhibition spaces would tell the story in a comprehensive way for the first time.
"UNTOLD isn't just about the past - it's about engaging people today. Schools, community groups, and volunteers will play a key role in shaping how these stories are told."
UNTOLD chair Hugh Crossey thanked the British National Lottery for its financial support
"UNTOLD Stories of the Irish in the British Army will hopefully inspire people to see things differently and make meaningful connections across generations.
"Education will be at the heart of all the exhibitions, offering our visitors the chance to explore the lives of the Irish men and women who rose above divisions of class, politics and religion and overcame extremes of hardship to make an indelible mark on our history.
"In sharing these stories, UNTOLD seeks to contribute to ongoing peace and reconciliation across the island.
"We are already surprised at the number of people from a range of traditions who have discovered ancestral and family histories amongst Irish regiments in the British Army".
