Khorezm region, Khiva
Itchan Kala is the inner town (protected by brick walls some 10 m high) of the old Khiva oasis, which was the last resting-place of caravans before crossing the desert to Iran. Although few very old monuments still remain, it is a coherent and well-preserved example of the Muslim architecture of Central Asia. There are several outstanding structures such as the Djuma Mosque, the mausoleums and the madrasas and the two magnificent palaces built at the beginning of the 19th century by Alla-Kulli-Khan.
Historic Centre of Bukhara
Bukhara, which is situated on the Silk Route, is more than 2,000 years old. It is the most complete example of a medieval city in Central Asia, with an urban fabric that has remained largely intact. Monuments of particular interest include the famous tomb of Ismail Samani, a masterpiece of 10th-century Muslim architecture, and a large number of 17th-century madrasas.
Samarkand – Crossroads of Cultures
The historic town of Samarkand is a crossroad and melting pot of the world's cultures. Founded in the 7th century B.C. as ancient Afrasiab, Samarkand had its most significant development in the Timurid period from the 14th to the 15th centuries. The major monuments include the Registan Mosque and madrasas, Bibi-Khanum Mosque, the Shakhi-Zinda compound and the Gur-Emir ensemble, as well as Ulugh-Beg's Observatory.
