The Tian-shan corridor is one section or corridor of this extensive overall Silk Roads network. Extending across a distance of around 5,000 km, it encompassed a complex network of trade routes extending to some 8,700 km that developed to link Chang’an in central China with the heartland of Central Asia between the 2nd century BC and 1st century AD, when long distance trade in high value goods, particularly silk, started to expand between the Chinese and Roman Empires.

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.

From the ancient Neolithic tumulus of Saraikala to the ramparts of Sirkap (2nd century B.C.) and the city of Sirsukh (1st century A.D.), Taxila illustrates the different stages in the development of a city on the Indus that was alternately influenced by Persia, Greece and Central Asia and which, from the 5th century B.C. to the 2nd century A.D., was an important Buddhist centre of learning.

Tabriz has been a place of cultural exchange since antiquity and its historic bazaar complex is one of the most important commercial centres on the Silk Road. Tabriz Historic Bazaar Complex consists of a series of interconnected, covered, brick structures, buildings, and enclosed spaces for different functions. Tabriz and its Bazaar were already prosperous and famous in the 13th century, when the town, in the province of Eastern Azerbaijan, became the capital city of the Safavid kingdom.

Sulaiman-Too Sacred Mountain Kyrgyzstan dominates the Fergana Valley and forms the backdrop to the city of Osh, at the crossroads of important routes on the Central Asian Silk Roads. For more than one and a half millennia, Sulaiman was a beacon for travellers revered as a sacred mountain. Its five peaks and slopes contain numerous ancient places of worship and caves with petroglyphs as well as two largely reconstructed 16th century mosques.

The ancient capital of Samarra dating from 836-892 provides outstanding evidence of the Abbasid Caliphate which was the major Islamic empire of the period, extending from Tunisia to Central Asia. It is the only surviving Islamic capital that retains its original plan, architecture and arts, such as mosaics and carvings. Samarra has the best preserved plan of an ancient large city, being abandoned relatively early and so avoiding the constant rebuilding of longer lasting cities.

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.

Sarazm, which means “where the land begins”, is an archaeological site bearing testimony to the development of human settlements in Central Asia, from the 4th millennium BCE to the end of the 3rd millennium BCE. The ruins demonstrate the early development of proto-urbanization in this region.

Orkhon Valley clearly demonstrates how a strong and persistent nomadic culture led to the development of extensive trade networks and the creation of large administrative, commercial, military and religious centres. The empires undoubtedly influenced societies across Asia and into Europe and in turn absorbed influence from both east and west in a true interchange of human values. This culture is still a revered and indeed central part of Mongolian society and is highly respected as a 'noble' way to live in harmony with the landscape.

Mount Emei (Emeishan) is an area of exceptional cultural significance as it is the place where Buddhism first became established on Chinese territory and from where it spread widely through the East. The first Buddhist temple in China was built on the summit of Mount Emei in the 1st century CE. It became the Guangxiang Temple, receiving its present royal name of Huazang in 1614.
