Dura Europos
A number of different civilizations inhabited the prosperous ancient city of Dura Europos in eastern Syria. Currently, just a few well-maintained ruins are visible. Dura Europos was established around 300 BC by the Seleucid Greeks, one of the successor republics that developed after the death of Alexander the Great. They chose to site it in the middle of their two major cities and with a view of the Euphrates River.
The majestic ruins of Dura Europos serve as a reminder of its rich cultural and historical diversity today. The location is home to the remains of the world's oldest synagogue and what has been called the first church, in addition to Greco-Roman ruins comprising temples. Visitors can tour the massive defenses, including walls and fortifications, as well as the remains of the siege operations that destroyed the city. The steep cliffs above the Euphrates offer stunning vistas as well.
It is not advised for visitors to travel to Syria at this time due to the country's political climate. However, there are some knowledgeable tour operators, like Nawafir Travel & Tours, that can show you around the site while an expert is in the driver's seat.
