Kevin will travel the length and breadth of the country to uncover the stories behind some of Britain’s most remarkable buildings and structures, exploring why places as diverse as Coventry Cathedral and the Penguin Pool at London Zoo have been judged worthy of the highest level of protection. This is heritage with the doors thrown open, as Kevin is invited into parts of these structures the public never normally sees, as he meets the people who care for them and gets hands-on himself.


In the first episode, he raises Tower Bridge and descends into its Victorian engine rooms, and enters a church beneath which 1500 years of London's history lie buried. In the oldest continuously working theatre in the English-speaking world, Kevin tries out a piece of stage machinery that's still operating after more than two centuries.
Kevin goes behind the scenes at Chatsworth House, and visits Castell Coch, the Marquess of Bute's Victorian gothic fantasy, complete with painted monkeys and medieval extravagance. Kevin also takes a look at the Palace of Westminster, one of the nation's treasured icons, but now badly in need of repair.
