“Paris had its birth, as the reader knows, in that old island of the City which has the form of a cradle,” Victor Hugo wrote in The Hunchback of Notre Dame. This very island in the center of the city has held a number of key institutions, including the Palais de Justice (central court house) and the Police Headquarters, at 36 Quai des Orfèvres, setting for all of the Paris Homicide mysteries (and before that for Simenon's Maigret mysteries). Both the courts and the police headquarters are being relocated in the near future, and according to an article in The Local, the center of Paris could be preparing for a makeover.
The police headquarters is set to move to the 17th arrondissement on April 18th, 2017. According to a recent article in the satirical Canard enchaînée, the new buildings won't have a cafeteria until 2018, because it will share with the new Palais de Justice, which is slated for completion a year later. The temporary solution is a 2 km walk from the new building. As the French refer to cops as "poulets" (chickens), the paper couldn't resist a joke about the upcoming free-range chickens.
