Underground Cities: Mapping the tunnels transits and networks underneath our feet

About this book

With over 60 per cent of the worlds population living in cities the networks beneath our feet which keep the cities above moving are more important than ever before. Yet we never truly see how these amazing feats of engineering work. Just how deep do the tunnels go? Where do the sewers bunkers and postal trains run? And how many tunnels are there under our streets? Each featured city presents a skyline of the underground through specially commissioned cut-away illustrations and unique cartography. Drawing on geography cartography and historical oddities Mark Ovenden explores what our cities look like from the bottom up.
