Dardanelles

The Dardanelles (/dɑːrdəˈnɛlz/; Turkish: Çanakkale Boğazı, Greek: Δαρδανέλλια, Dardanellia), also known in Classical Antiquity as the Hellespont (/ˈhɛlᵻspɒnt/; Greek: Ἑλλήσποντος, Hellespontos, literally "Sea of Helle"), is a narrow, natural strait and internationally-significant waterway in northwestern Turkey that forms part of the continental boundary between Europe and Asia, and separates Asian Turkey from European Turkey. One of the world's narrowest straits used for international navigation, the Dardanelles connects the Sea of Marmara with the Aegean and Mediterranean Seas, while also allowing passage to the Black Sea by extension via the Bosphorus.
