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.

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.
