Azerbaijan — known as the Land of Fire because of its history of Zoroastrian fire worship — cast subtlety aside with the Flame Towers. The three structures, which opened in 2012, each rise 620 ft. (190 m) over Baku, the capital. At night their LED exteriors light up to depict flames, a waving Azerbaijani flag and other moving images. The towers house a Fairmont hotel, offices and a shopping center.
