Passagenwerk or Arcades Project was an unfinished project of German philosopher and cultural critic Walter Benjamin, written between 1927 and 1940. An enormous collection of writings on the city life of Paris in the 19th century, it was especially concerned with Paris' iron-and-glass covered "arcades" (known in French as the passages couverts de Paris). Benjamin's Project, which many scholars believe might have become one of the great texts of 20th-century cultural criticism, was never completed due to his suicide on the French-Spanish border in 1940. The Arcades Project has been posthumously edited and published in many languages as a collection of unfinished reflections. The work is mainly written in German, yet also contains French-language passages, mainly quotes. Source: Wikipedia (en)
