Panama City
Ships pass through Miraflores locks within sight of downtown. Around 14,000 vessels a year make the transit, each lifted 26 m over the continental divide.
Five places whose fortunes were made — or in one case unmade — by an artificial waterway cut for ocean-going vessels.
Ships pass through Miraflores locks within sight of downtown. Around 14,000 vessels a year make the transit, each lifted 26 m over the continental divide.
The northern gateway of the Suez Canal, and a free port. Around 12% of world trade passes the end of its main street.
The canal is too narrow for modern freight and now carries mostly tourist boats — a spectacular engineering achievement that arrived a few decades too late.
The Nord-Ostsee-Kanal carries more vessels each year than the Suez and Panama canals combined, linking the North Sea to the Baltic in 98 km.
The ship canal made an inland city the country's third-busiest port. Ocean vessels no longer come this far up, but the container terminal downstream still runs.
