FILE - May 10, 2011 file photo of Sultan Ahmed Mosque or Blue Mosque in Istanbul, Turkey. On a moonlit night in the backstreets of Beyoglu, one of Istanbul's oldest districts, the worn facades and sharp-angled shadows recall the mournful character of the city that Nobel-prize winning Turkish author Orhan Pamuk described in a memoir. New, brash Istanbul charges ahead, and it's harder to uncover those pockets of dark ruin that epitomize "huzun," the dense, communal melancholy that permeated the former imperial capital in Pamuk's work. As Turkey strives for global status, its leading city strains to channel expansion that threatens its heritage, environment and even its identity.(AP Photo/Burhan Ozbilici, File) less
