The new Archbishop of Canterbury will embark on a six-day pilgrimage to prepare for her installation service. Dame Sarah Mullally, along with her husband Eamonn, will walk the 140km (87 mile) route from St Paul's Cathedral in London to Canterbury Cathedral before the service on 25 March. It is the first time in modern history that an Archbishop of Canterbury has undertaken a pilgrimage of this nature in the lead-up to their installation. While walking the Becket Way, her group will join prayer services at churches, cathedrals and abbeys, as well as meeting with other pilgrims and visiting schools. Stops will include Southwark Cathedral, Aylesford Priory, the Shrine of St Jude in Faversham, Lesnes Abbey and Rochester Cathedral, Lambeth Palace says. The final stretch of the journey will see the pilgrims joined by David Monteith, Dean of Canterbury, and members of the Cathedral chapter to walk from the village of Chartham to Canterbury, arriving in time for evensong on Sunday, 22 March.…
