Pilgrims have been coming to the shrine at Knock in Ireland's County Mayo since 1879 when fifteen people allegedly saw a vision of the Virgin Mary, St Joseph and St John the Evangelist. Even the Pope has been there; making the trip for the shrine's 100th anniversary in 1979.
And today, Saturday Dec. 5, thousands more are expected.
They are coming in response to a prediction of a visitation by the Blessed Virgin by Dublin "spiritual healer" Joe Coleman and they will be staring at the sun in hopes of seeing the apparition for themselves.
A previous gathering there on October 31, led to at least 5 pilgrims being treated for solar retinopathy (eye damage caused by staring at the Sun).
