The team was projected onto the basalt rock as it was announced by Michael O'Neill
It has been 30 years since Northern Ireland last featured in a major tournament and the Irish FA have pulled out all the stops in announcing their squad for Euro 2016.
Manager Michael O'Neill announced the team on Saturday afternoon at the Titanic Quarter in Belfast and used the Giant's Causeway in Antrim to announce the team.
All 23 players were projected onto the basalt rock, in a late night recording that was shrouded in secrecy, until the team was announced.
Wigan striker Will Grigg is the notable inclusion in the squad, that was whittled down from 27 to 23. Manager Michael O'Neill admitted that Grigg's inclusion over Liam Boyce was the toughest decision he had to make.
The team have one final warm-up game before the tournament begins. They face Slovakia next Saturday in Trnava. Eight days later, Northern Ireland begin their Euro 2016 campaign against Poland in Nice.
