Panama Canal belongs to the Common Era — dated here to c. 1914 CE at Panama. Dates mark a scholarly centre of gravity (dedication, completion, or iconic phase), not a single foundation day.
A lock canal across the continental divide — ships climb a freshwater staircase between oceans.
How it amazes the brain
Gatun Lake, massive miter gates, and disease control that finally made the cut possible after French failure.

Geography rewritten. Every transit is still a logistics magic trick.
On dating
CE means years after the traditional birth of Christ. A monument listed as c. 1914 CE may have been founded earlier, rebuilt later, or become famous only in one phase. Engineering wonders (dams, tunnels, orbiting labs) are dated to opening or assembly.
