Non-Fiction

Discover the most diverse and curious cities and what they hide underground. We often know and recognize the skyline of cities but are completely unaware of what is hidden underground: discover the underground city in the Australian desert, learn about Canada's shopping arcades or New York's spider-web-like underground transport network, and audacious underground constructions such as the Channel Tunnel linking the UK to France.
