Today is the centenary of the Carlingford Lough Connemara and Retriever tragedy.
The collision of the two sea vessels resulted in the worse tragedy recorded in the area with ninety four deaths and one survivor.
A memorial plaque will be unveiled on Dublin bridge later.
This evening at 8:30pm, the time of the tragedy, churches across the area - north and south of the border - will ring their bells in memory of those who died.
Newry Maritime Association spokesman James McAreavy says it will be a moving reminder.
Speaking to Q Radio's Iveren McCallion he said, "We thought it would be a very fitting and a very poignant and an all-inclusive tribute to all the victims - the ninety-four victims of the tragedy."
