Highlights of Silk Road

Yazd is a desert city that was a major centre along the Silk Road and is the centre of Zoroastrianism, Iran's state religion before the arrival of Islam and a belief which predates Christianity. Over 10,000 believers still reside in the city today. Here the Towers of Silence on a hilltop was the traditional Zoroastrian burial ground, where bodies were left to be eaten by vultures. The Zoroastrian Fire Temple has a flame that has burned for over 1,500 years. Yazd is also renowned for its wind towers or badgirs which captured breezes and cooled living quarters below. The old town of Yazd is perfect for exploring on foot amidst the clay brick houses, ancient Islamic buildings and labyrinthine of narrow alleyways. Other notable attractions include the Jameh mosque with its twin 48 metre minarets, the Doulat Gardens and the Amir Chakhmaq mosque.

Esfahan is Iran's pearl, one of the finest places in the Islamic world and one of the great destinations in world travel. Although it dates back to the beginning of the Islamic period, Esfahan reached its peak under Shah Abbas the Great when he moved his capital here at the beginning of the 17th century. Esfahan's most impressive site is the enormous and spectacular Royal Square or Meidan Eman, over 80,000 square metres and the second largest city square in the world. The square, built as a royal polo ground and once home to entertainers, preachers and Silk Road caravans, is bordered on each side by four monumental buildings. The Mosque of Sheikh Lotfollah is renowned for its beautiful dome and exquisite tile work. The Ali Qapu Palace was developed from an earlier Timurid palace and was used by the Shah to receive guests and foreign dignitaries. It is renowned for its superb plaster works and paintings and has a balcony overlooking the square. The magnificent Royal Mosque and the Portico of Qaysariyyeh complete the historical masterpieces. The Imperial Bazaar leads from the square to the north, a labyrinth of alleyways selling carpets, sweets and spices, tiles, jewellery and bright clothes. Other buildings of note include Vank Cathedral in the Armenian quarter of Jolfa, Chehel Sotun Palace also known as 40 Columns Palace due to the reflection of its 20 columns in waters of its fountain and the shaking minarets of Minar-e Jonban. The historic bridges of the Zayandeh River include Si o Se Pol (the Bridge of 33 Arches) and the Khaju Bridge.

Istanbul

Turkey's most important city spans Europe and Asia across the Bosphorus and has been capital of three empires - Eastern Roman, Byzantine and Ottoman throughout its history (including its previous incarnations as Byzantium and Constantinople). This has left it with an incredibly rich historical heritage that makes it one of the great cities of the world. The Blue Mosque is perhaps the city's most famous sight, built by the Sultan Ahmet I in the 17th century, with a stunningly impressive scale and elegant design. Aya Sophia was built as a Byzantine Christian church in the 6th century, converted to a mosque after the Islamic takeover in the 15th century and now a museum. Its huge dome and walls include some superb mosaics. The 4th century Hippodrome of Constantine was the site of political demonstrations, chariot races and polo matches. Topaki Palace, built in Islamic style, was the home of the Ottoman sultans for four centuries. Other buildings of note include Suleymaniye Mosque, the Kariye Camii church and the ancient ramparts and aqueduct. One of Istanbul's most famous attractions is the vast Grand Bazaar, a labyrinth of some 4000 covered shops, cafés and restaurants, where you can haggle for jewellery, clothes, sweets and spices.
