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.
