My attempt to visit Paris's Art Nouveau public toilets, alongside the church of La Madeleine, was foiled as they have now been closed. Although they are listed buldings, the city sealed them off with metal gates as a cost-cutting measure. How lucky that my visit was motivated by curiosity rather than desperation! Even more luckily, there was some compensation: the extravagant murals at the entrances are still visible.
As the tiles boast, the toilets opened in 1905. They were the first such conveniences in France, copying London facilities operating since the previous century. Inside were mahogany doors with stained glass panels, opening into generously-sized cubicles with washbasins; there was even a shoe-cleaning seat in the middle of the room. The automated 'sanisette' cubicles which replace all that luxury seem a very inferior alternative.
