Five historic maps are explored in detail, as are five new digital maps that push the limits of cartography.
"The British Library is home to a staggering 4.5 million maps, most of which remain hidden away in its colossal basement, and the programme delves behind the scenes to explore some amazing treasures in more detail. This is the story of three maps, three 'visions' of London over three centuries; visions of beauty that celebrate but also distort the truth. It's the story of how urban maps try to impose order on chaos."
Video documentaries on these maps are airing, but are not currently available online.
