Alice Roberts embarks on a quest for the truth behind 
Britain’s Holy Grail legend. Beginning on the Isle of Wight, 
she explores the story of Joseph of Arimathea and the 
Grail. Uncovering local folklore and learning how oral 
traditions change stories before heading to Glastonbury. 
Did Joseph bury the Grail beneath the Tor? Archaeologist 
Cheryl Green and Dr Andrew Boakye weigh the legend’s 
historic plausibility.
In Oxford’s Bodleian Library, Dr Dominic Selwood explains 
how the Grail link was added much later in literature, and 
how the Grail Romances linked in King Arthur. Heading 
to Wales, she finds passionate locals and unearths 
legends of sacred vessels and ancient cauldrons. Back 
at Glastonbury, she investigates Arthur’s grave, joining 
archaeologist Miles Russell on the Tor at sunset. 
The trail leads to London and the Knights Templar, 
sparking questions about their possible Grail links. 
Heading to Scotland, Alice examines Holy Relics, 
investigating the conspiracy of Rosslyn Chapel 
concealing the Grail. Alice examines a wooden bowl 
found under the chapel in 1993. With scientific 
tests dating it post 1666, its origins remain unclear. 
Ultimately, in Temple, Edinburgh, Alice finds peace 
among Templar ruins, revealing that the Grail’s true 
power may lie in personal discovery… not physical proof.
