Strait of Dover

The Strait of Dover is a narrow channel that separates the southeastern coast of England from northern France. It connects the North Sea to the English Channel, measuring about 21 miles (34 kilometers) at its narrowest point. This strait is one of the busiest shipping routes in the world, allowing ships to travel between the Atlantic Ocean and the North Sea. Its proximity has historically made it strategic for trade, defense, and migration. Despite its busy navigation, the strait is still a natural boundary between two countries, with the iconic White Cliffs of Dover watching over the English side.
