A visual and anecdotal exploration of the curious worlds hidden beneath our feet, including ancient cities, salt mine cathedrals, underground amusement parks, and more. From bone-filled catacombs to sculpted salt churches to hand-carved cave complexes large enough to house 20,000 people, Underground Worlds is packed with more than 50 unusual destinations that take some digging to find. Award-winning travel writer David Farley revels in the unexpected, whether it is a cave city in China which houses one of the world's largest collections of Buddhist art or an old salt mine converted into a theme park in Romania. Stunning photos help readers see places they could not even imagine, such as a three-story underground train station in Taiwan that is home to the a 4,500-panel "Dome of Light" that is the largest glasswork on Earth, as well as secret spaces, such as an ornate temple built beneath a suburban home in Italy. Throughout the fascinating text are themed entries of underground systems such as the 2,500-year-old water tunnels of Kish Qanat in Iran or engineering marvels like the New York City steam tunnels.

With over 60 per cent of the world’s 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.

New ideas and technologies are transforming the ways we build and inhabit underground space. This book explores how these innovations can help to make our increasingly dense, climate-stressed cities both more resilient and more of a pleasure to live in. While it sets out practical design approaches, Underground Cities is not a technical manual. Designed for everyone with an interest in the future of our cities, it is beautifully illustrated and written in an accessible style that draws on the rich tradition of underworlds, both real and imagined, in art, history and poetry. Global in scope, the book ranges across continents as it surveys the vast expansion in the potential of the underground. The opening section, 'A New Frontier', looks at two pioneering cold-climate cities, Montreal and Helsinki, which developed new uses for the underground from the 1960s on. The closing section, 'Looking Forward', offers glimpses of the city of the future - of what we might be able to achieve in the next 50 or 60 years. Focusing on Hong Kong, Singapore and Tokyo, it shows projects that are going deeper, achieving a greater synergy of uses and preparing the way for new urban forms. In between, it reviews a range of innovative ideas and presents buildings and projects by leading international architects and artists, among them Jun'ya Ishigami, James Turrell, Dominique Perrault and Thomas Heatherwick, which highlight the advances in technology that are making it possible to bring the elements of nature - light, air, vegetation - deep underground. Works include a subterranean oasis, a refuge from the desert heat; a museum extension that deploys light and colour to define space; a multi-modal underground transport hub that evokes the arcades of nineteenth-century Paris, but with an added profusion of plants; and a troglodytic house and restaurant, sunk into the earth to create atmosphere.

Humans have "gone underground" for survival for thousands of years, from underground cities in Turkey to Cold War-era bunkers. But our burrowing roots go back to the very beginnings of animal life on Earth. Many animal lineages alive now—including our own—only survived a cataclysmic meteorite strike 65 million years ago because they went underground.On a grander scale, the chemistry of the planet itself had already been transformed many millions of years earlier by the first animal burrows which altered whole ecosystems. Every day we walk on an earth filled with an underground wilderness teeming with life. Most of this life stays hidden, yet these animals and their subterranean homes are ubiquitous, ranging from the deep sea to mountains, from the equator to the poles. Burrows are a refuge from predators, a safe home for raising young, or a tool to ambush prey. Burrows also protect animals against all types of natural disasters. Filled with spectacularly diverse fauna, acclaimed paleontologist and ichnologist Anthony Martin reveals this fascinating, hidden world that will continue to influence and transform life on this planet.

A round-the-world adventure exploring curious worlds hidden beneath our feet, from underground burrows to ancient cities and shopping malls. Fourth book in the successful Walk this World series. This stunning lift-the-flap book takes the reader on a journey all around the globe and deep underground. There they'll find amazing hidden worlds, teeming with life - from prairie dog towns and ant cities, to opal mines and treasure-filled tombs. Each spread is bursting with details and has new surprises to discover in the cutaway artwork and under the flaps. With so much to see and explore, this is a perfect gift for young adventurers.
