The Panama Canal opened for business on August 15, 1914. It was the technological marvel of its time and is still pretty impressive. The canal provides a short-cut from the Atlantic Ocean, via the Caribbean Sea, to the Pacific Ocean, avoiding the much longer trip around South America. The canal consists of three sets of locks on the Caribbean side and three sets of locks on the Pacific side with two artificial fresh water lakes in the middle.
The Panama Canal is a double set of canals, see the images below. Because we did not debark the ship, I photographed a different cruise ship, the Celebrity Century, which was in the right lane ahead of our ship. Our ship took the left lane.
