The Sagrada Família and Hello Kitty

Max Pearson presents a collection of the week's Witness History episodes.

We hear the story of the largest unfinished Catholic church in the world and the creation of one of the most recognisable characters on the planet.

Plus, an amazing first hand account of the expulsion of German-speakers from Czechoslovakia at the end of the Second World War, the man behind Dignitas, the assisted dying organisation in Switzerland, and the son of a Guatemalan president who was overthrown in an American-backed coup in the 1950s.
