Overview: Ifor sets out to understand the appeal of shrines. For those outside the Catholic and Orthodox church there is something vaguely unsettling about shrines. How can venerating the bones of a dead person bring you closer to God? From the unlikely starting point of Marc Bolan's roadside shrine in Barnes, Ifor embarks upon perhaps his most surprising journey. Along the way he learns that Scotland's largest city only exists because of a shrine and visits the newly-renovated shrine of St David in Wales. At St Albans Cathedral, he learns that shrines are slowly but surely starting to creep back into the Anglican mainstream and that rather than meeting resistance, they are being actively embraced. After viewing a genuinely shocking relic in Westminster Cathedral, Ifor meets with the Catholic archbishop Vincent Nichols, who has a radical theory about how the return of shrines represents the final chapter of the Reformation, and that is all down to Princess Diana.
