Ancient columns stand at the Al-Mina archaeological site

• Ancient columns stand at the Al-Mina archaeological site, South Governorate, Tyre, Lebanon, 
• on May 3, 2017. Tyre, on the Mediterranean Sea, served as one of several ports at
•  the western end of the Silk Road. Traders, having reached this point, might unload 
• their goods onto a waiting ship, or board the vessel themselves to continue westward—or,
• turn around and head back toward Xi'an once again, more than 4,000 miles away, as the crow flies
