At the northern end of Parc de la Villette, the huge City of Science & Industry has all sorts of high-tech exhibits. Bring a picnic and spend the day here.
There are two main exhibit areas inside, in addition to a planetarium, two cinemas, a tiny aquarium and a 1950s French Navy submarine with specific admission fees and hour of visiting.
The most notable features of the "bioclimatic facade" facing the park are Les Serres - three greenhouse spaces each 32 metres high, 32 metres wide and 8 metres deep.
