Where did the Silk Road run?

The 4,000-mile trade route called the Silk Road joined the ancient kingdoms of China and Rome.

It started in Siam, followed the Great Wall of China to the northwest, bypassed the Takla Makan Desert, crossed the Pamir Mountains, passed through Afghanistan, and ended at the Levant.

Goods were then transported across the Mediterranean Sea to Greece and Rome. The Silk Road is now partially preserved as a highway.
