This weekend marks 100 years since the sinking of two ships which departed from Liverpool for Waterford, causing the loss of 83 lives.
The SS Formby and the SS Coningbeg were torpedoed on December 15th and 17th ,1917, in a World War 1 attack.
67 of those who perished were from Waterford.
A series of talks on these tragic events takes place at City Hall on Friday from 7.30pm, preceded by a tour of The Waterford Museum of Treasures at 4.30pm, where memorabilia from the ships are housed.
There will then be an ecumenical service to honour those who died, at 12pm Saturday in Christchurch Cathedral.
All events are free.
WLR will also broadcast an hour-long documentary on Dec 29th from 6pm, called ‘Sink on Sight’ about the tragedy.
