Croagh Patrick, known locally as the Reek, is a mountain in the west of Ireland in County Mayo.
Croagh Patrick has been a pilgrimage site for hundreds of years in honour of Saint Patrick, Ireland's patron saint, who fasted for forty days on the summit of the mountain in 441 and built a church there. On 'Reek Sunday', the last Sunday in July every year, over 25,000 pilgrims climb the mountain, many of whom barefoot.
The village of Murrisk is situated at the foot of the mountain.
