Bettany Hughes' Treasures of the World

In Turkey, Bettany visits the underground cave cities of Cappadocia and the 10,000-year-old temple and settlement at Göbeklitepe. In the east of the country, she visits Urfa, one of the most significant pilgrimage cities of the Middle East, believed by some to be the birthplace of the Biblical figure Abraham, and hikes up to Mount Nemrut, the highest open-air museum in the world.
