A ceremony took place over the weekend to mark the 50th anniversary of the Castleblayney bombing.
One man, 56-year-old Patrick 'Packie' Mone was killed when a no-warning car bomb exploded outside the Three Star Inn on Main Street at 8.20pm on March 7th 1976.
The explosion also left 17 other people injured.
A well-attended wreath-laying ceremony took place on Saturday afternoon to mark 50 years since the Castleblayney bombing.
The commemoration was attended by a number of local councillors and by local Sinn Féin TD Matt Carthy.
It is believed that the intended target on that faithful evening was the Dublin-Derry bus which was due to arrive at the location at 8.20pm, but which was two minutes late after it was held up by a checkpoint.
Cathaoirleach of the Carrickmacross/Castleblayney MD Cllr Paul Gibbons who laid a wreath during the ceremony says the event was a significant one and it was a time to think of Packie and his family.
The Cathaoirleach of Monaghan County Council PJ O'Hanlon says events like the 50th anniversary of this bombing highlights to younger people what times were like in the border region. He says we should never take peace for granted.
Local councillor Aidan Campbell paid tribute to the numbers that turned out in support of the Mone family. He said it highlights how the town has come back even more resilient for some very dark days like the evening Packie was killed on the Main Street.
Margaret Urwin from Justice for the Forgotten also addressed those who gathered for Saturday's memorial.
She said you have to remember like so many other families, the Mone family to this day have never got justice and their fight for answers and closure continues.
