A strait is a narrow body of water connecting two larger bodies of water. How narrow?
The world’s narrowest strait that can be used by ships separates the mainland of Greece from an island named Euboea, which is about the size of Long Island. At one point, this strait, called the Euripus Channel, is just 45 yards wide!
In the middle of the strait, not far from its narrowest point, stands a large rock with a ruined castle. A bridge connects the rock with Euboea, and another bridge connects it to the Greek mainland. A bridge has stood on this site since the fifth century B.C.!
