The world's largest start-up campus was unveiled by French president, Emmanuel Macron, in mid-2017. At any one time, some 3000 resident entrepreneurs from all over the world beaver away on ground-breaking new ideas and businesses, supported by 30 high-tech incubators and accelerators in this unique start-up ecosystem. Guided tours take visitors on a 45-minute waltz through the gargantuan steel, glass and concrete hangar – a railway depot constructed in 1927–29 to house new trains servicing nearby Gare d'Austerlitz.
Two public passageways divide the 'Create' zone (where all the serious action happens) from the 'Share' zone – embracing the vast lobby with monumental Jeff Koons Playdough sculpture and the Anticafé co-working space where hipsters pay €5 an hour to drink coffee, snack and plug in – and the 'Chill' zone. The public Chill zone stars gigantic restaurant (Europe's largest), La Felicità.
Guided tours can only be booked online; reserve well ahead.
