Wreaths have been laid at the graves of the victims of the Church Street Tenement Collapse in Dublin 100 years ago today.
On 2 September 1913, 66 and 67 Church Street collapsed, killing seven people, including three children.
Eight other people were seriously injured and 11 families were left homeless.
The disaster, which was the worst single tragedy of the Dublin Lockout, shone a harsh spotlight on housing conditions in Dublin's slums.
It came less than 48 hours after police baton-charged crowds on Sackville Street (now O'Connell St), injuring 600 strikers in what became known as Bloody Sunday.
