Taoiseach Enda Kenny and Republic of Ireland soccer manager Giovanni Trapattoni have taken part in a charity climb on Croagh Patrick in Co Mayo.
An estimated 1,500 people joined Mr Kenny and Mr Trapattoni on the trek.
Many supporters were wearing their green jerseys ahead of the Euro 2012 Championships.
Mr Trapattoni said he shared his birthday with St Patrick's Day and feels the saint is protecting him in his personal and professional life.
The Irish soccer squad will make their own pilgrimage to Poland in June for Euro 2012.
Mr Trapattoni described Croagh Patrick as a special place, and said he hopes this visit will bring luck to the boys in green.
The charity initiative will benefit Mayo Mountain Rescue, Western Alzheimers, Mayo Roscommon Hospice, Western Care and the John Giles Foundation.
