The first funerals are being held for the men who died in the country's worst road crash.
Shattered communities in Co Donegal will come to a standstill to pay their respects on Wednesday, and well-wishers are expected from across the country.
Seven young friends had been watching Spain's victory in the World Cup final before dying instantly along with another man in the horror crash on the Inishowen peninsula.
Some of the youths, aged between 19 and 23, left their cars behind to take a lift after socialising in the village of Clonmany minutes before the crash.
Eight people were packed into a Volkswagen Passat which clipped a Renault Megane on the country road to Buncrana before crashing head-on into a Toyota Corolla 200 yards away. The Volkswagen and the Toyota ended up in a ditch.
Alcohol was not a factor, Gardai said. The driver of the third car, who was alone, was also killed.
Hugh Friel, a 66-year-old man from Dunaff, Clonmany, was returning home in his Corolla after an evening at bingo in Buncrana when he was involved in the accident.
His will be the first funeral, to be held near his home in St Michael's Church, Urris, and he will be buried in the adjoining cemetery.
A requiem will be said for Mark McLaughlin, 21, from Ballynahone, Fahan, at St Mary's Church with burial in the cemetery.
