The comedian returns with the programme celebrating traditional crafts, beginning with blacksmith Ian Thackray giving juniors Bran, Brad and Georgia a masterclass. Bill also visits Ironbridge in Shropshire.

Simon Smith gives a stone-carving masterclass to three novices, while Bill visits Salisbury Cathedral, home to Britain's tallest stone spire

In the third Masterclass, three junior mosaic enthusiasts take part in a workshop hosted by mosaic royalty Paul Siggins, while Bill visits the iconic St Paul's Cathedral in London for its distinct mosaics, in which you can see the look of the cathedral evolve from the original designs by Sir Christopher Wren, austere and restrained, to the Victorians who injected a bit of sparkle to the domes!
