Croagh Patrick (Irish: Cruach Phádraig) is a 764 m (2,510 ft) mountain in the west of Ireland and an important site of pilgrimage. It is located 8 km (5 miles) from Westport, County Mayo above the villages of Murrisk and Lecanvey. On "Reek Sunday", the last Sunday in July every year, over 25,000 pilgrims climb the mountain, many of whom climb barefoot. The mountain forms the south part of a U-shaped valley created by a glacier flowing into Clew Bay in the last Ice Age. Croagh Patrick is part of a longer east-west ridge; to the west is the mountain Ben Goram. Croagh Patrick derives its name from the Irish Cruach Phádraig ("Saint Patrick's mountain") although it is known locally as the Reek, and some mistakenly refer to the place as Mount Coagh (or Croach) Patrick. In the Annals of Ulster entry for the year 1113, the mountain is named Cruachán Aigle (Eagle Mountain).
A seam of gold was discovered in the mountain in the 1980's: overall grades of 0.5 ounces of gold per ton in at least 12 quartz veins, which could produce 700,000 tons of ore. Local authorities elected not to mine it, deciding that the gold was "fine where it was". Read more...
