Constanta is the oldest city in Romania, located on the western coast of the Black Sea. Originally called Tomis, it has a long history dating back over 7,000 years. Tomis was an important Greek colony and trade hub from the 7th century BC. It later came under Roman rule and was renamed Constantiana in the 4th century AD. Constanta saw significant development in the late 19th century as Romania's main port on the Black Sea, driving economic growth through maritime trade. Today, Constanta remains an important cultural and economic center as well as Romania's largest port.
