The Panama Canal is a 77.1 km ship canal in Panama that connects the Atlantic Ocean to the Pacific Ocean. The canal cuts across the Isthmus of Panama and is a key conduit for international maritime trade. There are locks at each end to lift ships up to Gatun Lake, an artificial lake created to reduce the amount of excavation work required for the canal, 26 meters above sea level.

The great engineering achievements of the modern world are more than purely functional. The visionaries who dreamed up their imposing shapes used art and science to create structures of dramatic beauty. Our bridges, dams, and skyscrapers, dominate our landscapes, as the pyramids dominated those of ancient Egypt. They're testaments to the creative genius of humankind.
