Palais de la Découverte (Palace of Discovery)

Palais de la Découverte (Palace of Discovery) Review

This science museum and planetarium behind the Grand Palais has a wide variety of exhibits on subjects from electricity to climate change to nuclear physics. After a merger with Cité des Sciences in 2009, the Palais's days were said to be numbered but, as of this writing, the museum is still open. Built for the 1937 World's Fair, the museum bills itself as the first interactive museum. There's also a planetarium with several shows daily.
