Over €120,000 was spent preparing Skellig Michael last year, despite the island not opening to visitors.
The Office of Public Works, which has responsibility for the UNESCO World Heritage Site, has released the cost of supplies and services incurred during 2020.
The island's popularity has grown considerably in recent years; over 16,000 visitors landed on the island in 2019.
In August 2020, after the OPW had confirmed that Skellig Michael would remain closed for the year, Radio Kerry reported that €40,000 had been spent at that stage maintaining and preparing the island.
However, there were further costs incurred despite the island remaining closed.
During the period July 9th-December 31st, a further €84,000 was spent.
Nearly €17,000 was spent on stone, €10,000 on scaffolding, €8,000 on electrical and technical equipment, €2,500 on building supplies, over €1,000 on timber and €676 on steel.
In terms of services, €15,000 was spent on consultancy, €13,270 on audio visual services, €8,600 on archaeological services and nearly €3,000 on health and safety.
In total, over €120,000 was spent preparing Skellig Michael last year.
