On this day in 1682, Louis XIV of France, le Roi Soleil, the Sun King, moved into a new crib.
Versailles was designed to awe France's unruly nobility and peasantry. SWPL tourists have been visiting ever since. If you go, make sure that it's on a Sunday, the only day when they turn the fountains on. Pretty cool SWPL, actually.
And on this day in 1994, the Chunnel - the Channel Tunnel connecting England and France - opened.
It's a miracle of modern engineering, as are the high speed TGV (Train à Grand Vitesse; French high speed Bullet Trains). Both are unfortunately wildly uneconomical. The company that runs the Chunnel only sporadically makes a profit, and has had to restructure its debt obligations (under government guarantees) with a rather tedious regularity. Ridership peaked in 1998, oddly coinciding with the trip of the Borepatch clan.
Somewhere we have a child's complementary backpack (no doubt filled with plastic Pokemon toys) and a Eurostar "In Flight" magazine as souvenirs. Very SWPL.
