This brand new series is real treat for the history buffs. Historian Simon Sebag Montefiore traces the sacred history of Istanbul. The Turkish capital was once described as the 'city of the world's desire', having been the focus of three faiths - Paganism, Christianity and Islam - and the stage for some of the fiercest political and religious conflicts over the past 2,500 years. Simon begins by uncovering its Greek roots and maps its transformation into the capital of the Roman Empire by Constantine the Great.
