Filled with fun facts and unbelievable photography, Subterranea is a below-the-surface exploration of the world's most spectacular underground spaces. Geographer and storyteller Chris Fitch peels back the outer layer of the earth and reveals the fascinating hidden underground spaces you can't see from above the ground. These incredible places include poisonous caves in Mexico where the toughest fish in the world manage to survive; the magnificent Roman sunken palace that was lost beneath the streets of Constantinople for centuries; the "Door to Hell" that was accidentally created by Soviet gas explorers in the 1970s and has been on fire for nearly half a century; and the drug-smuggling tunnels between Mexico and the United States.

Lavishly illustrated and packed with maps and photographs of little-explored locations, Subterranea is the unique, untold, and utterly unforgettable story of our planet from the inside.
