THERE was Alice Roberts last month exploring the history of Norman Winchester for a Channel 4 show.

And now Sir Tony Robinson explores the Norman period’s greatest achievement, Winchester Cathedral.

A Channel 5 series called Britain’s Great Cathedrals culminates tomorrow, on Friday May 11 with an hour-long documentary exploring the building’s fascinating history

The six-part documentary series looks at the architecture and tells the stories and characters behind six of Britain’s cathedrals.

Other episodes have included York Minster, Canterbury, Salisbury, Durham and Liverpool cathedrals.

The Winchester Cathedral episode will span over 1,000 years, from the Anglo-Saxons to cathedral life today.

Viewers will have the opportunity to see priceless treasures from the cathedral collection, including the 12th-century Winchester Bible, and learn more about intriguing characters from the cathedral’s history, including the diver William Walker who famously saved the Cathedral from collapse ‘with his own hands’ by shoring up the foundations, working on his own in the watery darkness for several years before World War One.

Sir Tony’s quest to uncover the hidden history of the cathedral will take viewers on a journey of contrasts from spectacular architecture in the nave to a medieval sewer hidden beneath Cathedral Close.

The Winchester Cathedral episode will be broadcast on Channel 5 at 8pm on Friday 11 May. All previous episodes are available on My5.
