Bukharais 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. The Historic Centre of Bukhara, situated on the Silk Roads, is more than two thousand years old. It is one of the best examples of well preserved Islamic cities of Central Asia.
Bukhara was a long time an important economic and cultural center in Central Asia. The ancient Persian city served as a major center of Islamic culture for many centuries and became a major cultural center of the Caliphate in the 8th century.With the exception of a few important vestiges from before the Mongol invasions of Genghis Khan in 1220 and Temur in 1370, the old town bears witness to the urbanism and architecture of the Sheibani period of Uzbek rule, from the early 16th century onwards. The citadel, rebuilt in the 16th century, has marked the civic center of the town since its earliest days to the present.
Important monuments that survive from early times include the famous Ismail Samanai tomb, impressive in its sober elegance and the best surviving example of 10th century architecture in the whole Muslim world. From the 11th century Karakhanid period comes the outstanding Poi-Kalyan minaret, a masterpiece of decoration in brick, along with most of the Magoki Attori mosque and the Chashma Ayub shrine. The Ulugbek medresseh is a surviving contribution from Temurid. With the advent of the Sheibanids came some of the most celebrated buildings of Bukhara: the Poi-Kalyan group, the Lyabi-Khauz ensemble, the Kosh Medresseh and the Gaukushon medresseh in the Hodja-Kalon ensemble. Later buildings from this phase of Bukhara´s history include monumental medressehs at important crossroads: Taki Sarafon (Dome of the Moneychangers), Taki-Tilpak-Furushan (Dome of the Headguard Sellers), Tim-Bazzazan, and Tiro-Abdullah-Khan. In the early 17th century fine buildings were added, including a new great mosque, Magoki Kurns (1637), and the imposing Abdullaziz-Khan medresseh (1652).
However, the real importance of Bukhara lies not in its individual buildings but rather in its overall townscape, demonstrating the high and consistent level of urban planning and architecture that began with the Sheibanid dynasty. Bukhara is the most complete and unspoiled example of a medieval Central Asian town which has preserved its urban fabric to the present day.Between the 9th and 16th centuries, Bukhara was the largest center for Muslim theology, particularly on Sufism, in the Near East, with over two hundred mosques and more than a hundred madrasahs.Bukhara has preserved a great deal of its urban layout that dates from the Sheibanid period. Modern buildings have been erected in the historic centre over the past half-century that have destroyed the appearance of some quarters, but in others the medieval townscape has survived. The proportion of old structures, particularly the public and religious buildings, nonetheless remains high, and the historic centre is unquestionably of outstanding significance as an exceptional example of a largely medieval Muslim city of Central Asia.In the context of regarding the Historic Centre of Bukhara as an entire entity – expressed through a variety of attributes including urban setting, form and design, use of materials and techniques, functions and tradition – some factors can be recognized as having the potential to impact adversely on the authenticity of the property, namely: the diminishing use of traditional materials and traditional building techniques and introduction of new building materials, as well as new architectural details.
