The story behind it

The English Channel is about 560 km long. In the west it is up to about 240 km wide, but in the east, at the Strait of Dover, only 34 km of water separate England from France. The French call it La Manche, which means the sleeve, and the German name also comes from its sleeve-like shape. More than 500 ships pass through it every day, making it one of the busiest shipping areas in the world. Since 1994, trains have travelled underneath it through the Channel Tunnel. People have crossed it in many brave ways: in 1875 Matthew Webb swam across in 21 hours and 45 minutes, and in 1909 Louis Blériot flew over it in an aeroplane. The Channel Islands, such as Jersey and Guernsey, lie close to the French coast. Grey seals and harbour seals are often spotted in its waters.
