It accounts for 3.03% of Turkey's land area and 15% of its population. The largest city is Istanbul, which straddles the Bosporus between Europe and Asia. East Thrace is of historic importance as it is next to a major sea trade corridor and constitutes what remains of the once-vast Ottoman region of Rumelia. It is currently also of specific geostrategic importance because the sea corridor, which includes two narrow straits, provides access to the Mediterranean Sea from the Black Sea for the navies of five countries: Russia, Ukraine, Romania, Bulgaria, and Georgia. The region also serves as a future connector of existing Turkish, Bulgarian, and Greek high-speed rail networks.

The Rupel Gorge or Rupel Pass is a steep river valley in the northern part of Central Macedonia, immediately south of the Greek-Bulgarian border. It was formed by the Strymon River, which stems from the Vitosha mountains and flows into the Aegean Sea. The gorge is rich in biodiversity which may be endangered by the project to build the Motorway 25 which is a part of European route E79. Strymon enters from Bulgaria into Greece west of village Promachonas, going through Roupel Pass, that it opened up, between the mountains Belasica and Orvilos. Here the ground gets flatter so the Strymon loses speed and splits into two branches. The western branch goes to lake Kerkini and then flows southeast where it rejoins the eastern branch near to the village of Lithotopi.
