A hiker in Peru in 1996 stumbled across a hinge-less, handle-less door in a stone cliff. Named “The Gate of the Gods” by locals, it opened via a slotted golden disk. Even today, secretive, mysterious places exist worldwide. A chamber of skulls in the Swiss Alps. A trap-filled temple in Japan. Bachmann and Tucholke expose eighteen mysterious places in descriptions and lush photos. A book to get lost in.
