Pilgrimage

In this first episode, the intrepid seven arrive in Biarritz and make their way to the start of their pilgrimage, a small town in the foothills of the French Pyrenees, St-Jean-Pied-de-Port. They are shown a copy of the ancient Codex Calixtinus, a medieval guide to the route, before heading to the Pilgrims' Office where they register and collect their all-important pilgrim passports, which they'll get stamped where ever they stop along the way.

In this second episode, our seven celebrities travel from the region of Navarre to the start of the final 100km in Galicia. In Irache, to their great delight, Neil, JJ and Kate come across a fountain of wine, where thirsty pilgrims can drink straight from the tap. One hundred litres of wine a day are supplied free by a local vineyard, and priest Kate, who struggled through the Pyrenees, celebrates this kind of charity as a spiritual moment. She dismisses the notion that through pain comes a better understanding of God, and that self-denial is the way to salvation.

The group are now in Galicia, walking the last 100km to Santiago. Priest Kate still dreads the walk, but non-believer Raph is beginning to enjoy the opportunity it is giving him to appreciate his surroundings. They stop by a river and chat to Guy Hayward, who runs the British Pilgrimage Trust. He explains the meaning of river pilgrimage and encourages them to take a dip in the freezing water. Against his better judgement, Ed decides to join the swimming party, along with Kate, who is much happier in water than she is walking.

In this first episode, the intrepid eight arrive in Martigny, Switzerland, and find out for the first time who will be sharing their pilgrim adventure. They make their way by mountain train to the start of their pilgrimage in Orsieres, high up in the Swiss Alps. The Via is based on a journey taken to Rome in 990AD by Archbishop Sigeric of Canterbury, which crosses the Alps at 2,500m and goes over the Great St Bernard Pass. Like Napoleon, his 40,000 strong army and the pilgrims before them, the group also have to make their way up the challenging mountain path.

In this second episode, it is day four, and Stephen, Greg, Brendan and Les wake up in a yurt. They are all staying in a hostel on a Roman road in a tiny village in the Tuscan Appenines, and they are beginning to realise how important the simple life is to the pilgrim experience – especially when a donkey appears in the kitchen to try and eat their breakfast.

The celebrity pilgrims set off on the final challenging stretch of the Via toward Rome. When they receive an extraordinary invitation from the Vatican, emotions run high.

Journalist Adrian Chiles, former politician Edwina Currie, Olympian Fatima Whitbread, broadcaster Mim Shaikh, TV presenter Amar Latif, comedian Dom Joly and actress Pauline McLynn set out to cover sections of the Sultans Trail - a modern-day 2,200km pilgrimage across Eastern Europe that starts in Vienna and ends in Istanbul. Each has varying religions, with Dom and Pauline confirmed atheists. Starting in Serbia's capital Belgrade, they stay in basic hostels and sleep in shared dorms, acting as simple pilgrims traversing the ancient military route by rail and foot.

Life on the Sultans Trail begins to challenge the celebrities as Adrian Chiles tells the group he is struggling with the purpose of pilgrimage in the face of their experiences.

Keen to trace Columba's footsteps, they make tracks to Dunadd Fort, where Columba is thought to have visited the local king. In torrential wind and rain, everyone but Scarlett, who is still struggling with her leg, eventually makes it to the top.Continuing their search of the mighty monk, not far from the fort is an extraordinary ancient place of worship.

As they question the monks about their life choices, Monty, Louisa, Will and Nick fruit pick in the orchards, while Lawrence, Shazia and Scarlett start cooking dinner. But over supper, and after attending a service conducted in Latin, the group's first proper argument erupts over a few misplaced words.By the following morning, all tensions are forgotten, and the pilgrims head off to Forres, a nearby ancient town dating back to around AD900. Louisa, Shazia, Scarlett and Will discover the Witches Stone, a memorial to so-called witches killed in the area during the Middle Ages. Meanwhile, Lawrence, Monty and Nick seek out Sueno's Stone, a famous Christian Pictish monument thought to be evidence that, three centuries after Columba's death, Christianity had reached the territory inhabited by pagan Picts.The pilgrims head west across the Highlands and catch a ferry to the Outer Hebrides and the Isle of Lewis. In Stornoway, Shazia takes the chance to pray at Britain's northern-most mosque, taking Nick and Louisa with her. After the service, they're invited to stay for tea when they find out more about this small, friendly Muslim community. Once reunited with the other pilgrims, they head to the Calanais Stones, which are older than Stonehenge. While Lawrence ponders how Columba would have reacted to these pagan megaliths, Shazia shares that with any place of pilgrimage, its significance is not what it is, but the faith you have in it.The pilgrims then start heading back south on the Scottish mainland towards the Inner Hebrides. On the way, they stop off for a wet and wild walk in Glen Nevis in the shadow of Ben Nevis, the highest mountain in the UK, and with Columba's Isle now only two days away, their thoughts start turning to the end of their pilgrimage and their own personal spiritual journeys.Another ferry ride gets them to the Isle of Mull - just a hop away from Iona - and their last overnight stop, where they sit down together to celebrate their journey and Columba. Early the following morning, day 15 of their pilgrimage, local boatmen take them on the final leg of their pilgrimage, from Mull to the tiny island of Iona.The current abbey on Iona was founded in the 13th century over the foundations of Columba's original 6th-century monastery, but it was Columba's settlement which made Iona an island famed for its scholarship and culture. The pilgrims visit the shrine where it's most likely Columba was buried, and a last walk to the hill of Iona brings about an emotional farewell to their pilgrimage, with the final words belonging to Nick, who salutes the memory of Columba and his achievements.
