La Cité des Sciences et de l'Industrie

This ultra-modern science museum pulls in five million visitors a year. Explora, the permanent show, occupies the upper two floors, whisking visitors through 30,000sq m (320,000sq ft) of space, life, matter and communication: scale models of satellites including the Ariane space shuttle, planes and robots, plus the chance to experience weightlessness, make for an exciting journey.

In the Espace Images, try the delayed camera and other optical illusions, draw 3D images on a computer or lend your voice to the Mona Lisa. The hothouse garden investigates developments in agriculture and bio-technology.
