In the latest leg of Dan Cruickshank's journey Around the World in 80 Treasures, our intrepid presenter hits some of the most mysterious and secret countries in the world - where the weary western traveller cannot be sure of a warm welcome. But he's in for a surprise as he is accosted by young girls in Bukhara and Persian carpet sellers in Iran. He couldn't be more welcome if he tried!
Tile-making in Samarkand, the extraordinary Trading Domes of Uzbekistan and the Fire Temple of Azerbaijan take Dan to some incredible but least visited in the world. There is also a real mystery to solve as he gingerly edges himself up a cliff-face towards the biggest archaeological puzzle of the 19th century, the Bisitun carvings.
After the pleasures of Iran, Dan heads for one of the glories of the ancient world - the great city of Persepolis - vanquished by Alexander the Great in 330BC. In its day it was the most beautiful city in the world and there's more than enough left to savour the brilliance - like the Palace of One Hundred Columns and the Gate of All Nations.
Lastly Dan hit Damascus in Syria and one of the most exotic souks - or markets in the world. Worn to a frazzle he heads for the local hammam, the town steam bath, for some well-earned rest and relaxation
