This is the book for the curious that highlights the 100 most secretive, intriguing places in the world. The sites range from acknowledged, high-security locations such as Coca-Cola's secret recipe vault in Georgia and the world’s largest ammunition storage facility at Hawthorne Army Depot in Nevada to unacknowledged, mysterious locations such as Moscow’s Soviet-era Metro-2 and the Bilderberg Group’s headquarters, rumored to be in the Netherlands. Other curiosities include the tomb of Genghis Khan, Sonoma’s Bohemian Grove, and the mysterious buzzing broadcasts by the Russian Cold War-era UVB-76 radio transmitter. Each entry provides the reader with a general geographic location and a brief, easily digestible summary of its history and speculative purpose—some locations are so secret that their entries lack even a whit of pictorial evidence. Softcover; 255 pages. 9 3/4" H x 7 1/4" W x 3/4" D. (1 3/4 lbs.)
