Underground Worlds: A Guide to Spectacular Subterranean Places

This visual and anecdotal book explores hidden underground worlds, including ancient cities, salt mine cathedrals, and underground amusement parks. Award-winning travel writer David Farley highlights over 50 unusual destinations, such as a cave city in China with a vast Buddhist art collection or a salt mine theme park in Romania.

Stunning photos showcase places like Taiwan’s three-story underground train station with the world’s largest glasswork, and secret spaces like an ornate temple beneath an Italian suburban home. The book also features themed entries on underground systems like Iran’s 2,500-year-old water tunnels and engineering marvels like New York City’s steam tunnels.
