The very first time I walked past the kiosque des noctambules (sure, I didn’t know the name back then either) I was perplexed by its colourful bejewelled state (who installed a glass bead-like art sculpture here?) and then noticed people coming up from underneath. Curious. A quick investigative effort revealed that it is the entrance to the métro station of Palais Royal-Musée du Louvre.

A contemporary art piece by Jean-Michel Othoniel, it was commissioned for the centenary celebration of the inauguration of métro in Paris. First introduced in 1900, métro line 1 was used to transport visitors of the city to enjoy the sites and sights during the Exposition Universelle of 1900. Back then, the line runs between Porte Maillot and Porte de Vincennes and Palais Royal-Musée du Louvre was one of the eight stops of the line. Pretty steep in history eh?
