March 31, 1889 –
French engineer Gustave Eiffel unfurled the French tricolor from atop the Eiffel Tower, officially marking its completion on this date, but its history dates back to Gallic times.
Documents that have been carbon-dated to roughly 200 B.C. indicate that King Catatonix of the Hellatians decreed, for no apparent reason, the construction of a big tower on the very site where the Eiffel Tower can be found today.

In Caesar’s Reflections on the Garlic Wars, the Roman general reminisces on having found “a curious wooden tower, tall and strange.” Baffled by this peculiar cultural monolith, and never happy to be baffled, he burned it to the ground.

Some four centuries later, with the western Roman Empire in collapse, wild-eyed Gallic nationalists rebuilt the tower using cheese instead of wood. They called it La Grande Fromage, from which we get the expression, The Big Cheese.
During subsequent invasions by and entanglements with Normans, Saxons, Angles, Ostrogoths, Visigoths, and Lolligoths, the Tower was repeatedly destroyed and rebuilt, always for no apparent reason. It had become a sort of habit by now, a national obsessive-compulsive disorder.
Rene Descartes was born on March 31, 1596. Descartes said that he existed because he thought, and although he said it in Latin everyone still had to admit that it looked like Reason had finally entered the world.
Therefore the Franks (who now called themselves the French, primarily to irritate Germany) lost interest in the tower, and at last abandoned the effort.
Unfortunately, in 1870 German chancellor Otto von Bismarck defeated the French army in a Sedan and laid siege to Paris. This made the French lose their heads (see also the French Revolution). They forgot all about Reason and made Gustave Eiffel build a Tower, this time using steel, which was stronger than cheese and not quite as flammable as wood. It stands to this day, a proud monument French culture, without which we would not have Champagne, Camembert, Brigitte Bardot, or Marcel Proust.
And so it goes
