Global undergrounds: exploring cities within - 57734

Rest your eyes long enough on the skylines of Delhi, Guangzhou, Jakarta - even Chicago or London - and you will see the same remarkable transformation, building after building going up with the breakneck speed of 21st-century urbanization.

But there is something else just as transformative that you won't see: sprawling networks of tunnels rooting these cities into the earth. 'Global Undergrounds' offers a richly illustrated exploration of these subterranean spaces, charting their global reach and the profound - but often unseen - effects they have on human life.
