In July 1964, after almost four years of hard work by a group of volunteers, the re-roofing of the main compound at Kilmainham Gaol was completed.
At a ceremony in Kilmainham Gaol the Chairman of the Restoration Committee, Mr. Sean Dowling, was handed the final slate by the Lord Mayor of Dublin, Mr. John McCann.
A total of 11,000 slates were put on the roof of the building covering an area of 5,100 square feet. The work, which began in September 1960, also involved the use of 400 panes of glass and three tons of putty.
A further three years work is required before the full restoration project is complete.
The film shows Mr. Sean Dowling placing the final slate on the roof of the main hall on 8 July, 1964 and was part of a RTÉ News report broadcast the following day on 9 July, 1964.
