The pilgrimage centre at Lough Derg has attracted a record number of applications for summer work.
140 people are looking for a job at the island site of St Patrick's Purgatory in Donegal, but there are just 50 positions available.
Lough Derg is known for its austere conditions, pilgrims have one daily meal of dry toast and black tea or coffee, unless they are on a 72-hour fast.
They are required to walk barefoot, and give up using their mobiles, laptops and MP3 players.
