Seven well known personalities with differing faiths and beliefs, meet in northern Portugal to tackle a modern-day Catholic pilgrimage.
Known as the Northern Way, their destination is the famous Sanctuary in the city of Fatima, where in 1917, three local shepherd children reported seeing apparitions of the Virgin Mary.
Word of the apparent sightings soon spread and on the date of the Virgin's last apparition, tens of thousands of people were drawn to the site. What they saw that day became known as the Miracle of the Sun, and the story made the international press. Fatima, once a small village, is now one of the biggest Catholic pilgrimage destinations in the world.
Travelling by foot, road and train, actor Su Pollard, who was raised in the Church of England; Jewish actress Rita Simons; Pentecostal born again Christian, Shane Lynch of Boyzone fame; reality TV star and influencer, Vicky Pattison, who is agnostic.
Plus, Bobby Seagull, a practising Catholic, maths whizz and TV personality; Nabil Abdulrashid, a comedian and practising Muslim; and Paralympian skier Millie Knight, who is non-practising Church of England, will live as pilgrims.
Pilgrimage: The Road Through Portugal begins Friday 7th April at 9pm on BBC Two.
