In pictures: St Thérèse relics
St Thérèse, a French Carmelite nun, widely known throughout the Catholic world as the Little Flower, was born in Alencon, Normandy and entered a Carmelite convent in Lisieux aged 15.
Born in 1873, Thérèse Martin was the youngest of nine children. Her parents were devout and she developed a vocation at a very young age.
She became famous after her death from tuberculosis in 1897, aged just 24, following the publication of her autobiography The Story of a Soul.
She was declared a saint in 1925 by the Roman Catholic Church and is regarded as one of the most popular modern saints. In 2009 her relics are touring England and Wales.
The tour will include 28 venues including 11 Catholic cathedrals and four convents. The tour includes York Minster, the only Anglican Cathedral to host the relics.
Throughout the tour of England and Wales thousands of pilgrims are expected to file past the relics.
Clergy from all faiths, school children and a large crowd greeted the relics as they arrived at York Minster.
A number of special events had been planned for the relics' visit to York Minster including a special ecumenical service of thanksgiving.
After processing down the Nave of York Minster they came to rest in the Lady Chapel.
The Minster was to remain open for the entire 18 hours of the relics' visit to enable as many people as possible to pay their respects.
On Friday October 2 hundreds of school children were expected at the Minster for a special service before the relics leave.
