Strait of Dover
The Strait of Dover or Dover Strait, historically known as the Dover Narrows, is the strait at the narrowest part of the English Channel, marking the boundary between the Channel and the North Sea, and separating Great Britain from continental Europe. The shortest distance across the strait, at 20.6 miles (33.2 km), is from the South Foreland, northeast of Dover in the English county of Kent, to Cap Gris-Nez, a cape near to Calais in the French département of Pas-de-Calais.
