The Silk Road was a network of trade routes connecting the East and West, and was central to the economic, cultural, political, and religious interactions between these regions. The Silk Road primarily refers to the land but also sea routes connecting East Asia and Southeast Asia with South Asia, Persia, the Arabian Peninsula, East Africa and Southern Europe.
This is a sample of cities/forts/stops that were on these routes throughout Asia. The chances are that if you visited a number of these cities you may have come across some of the ancient ruins although some of the buildings are well preserved or refurbished. mm
