Works currently under way
The capitals that support the dome are in poor condition, having been damaged by past events, including the 1922 civil war, when the roof and much of the structure were destroyed. A restoration programme was completed in 1932, but a century later each capital is being carefully removed for structural examination. Carving of replacement capitals has been taking place at Irish Natural Stone Ltd. Each capital has been hand-carved by a team of stonemasons, with over 1,000 hours of work required per capital. The masons use traditional techniques to mould and finish by hand blocks of Portland Stone, in accordance with best conservation principles.
