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.\u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":45665885356085,"sku":"ByrdShop_178131893X","price":48.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8139\/0901\/files\/9781781318935.jpg?v=1782412608","url":"https:\/\/atxbooks.com\/products\/underground-cities-mapping-the-tunnels-transits-and-networks-underneath-our-feet-9781781318935","provider":"ATX Books","version":"1.0","type":"link"}
