The original is in the "Musée des arts et métiers" Museum in Paris. I highly recommend to visit the museum if you ever are in Paris. It's filled with all kind of original scientific and engineering devices. Lavoisier device that split water into hydrogen and oxygen. Jaquard's weaving loom using punching cards. Clément Ader's late 19th century attempt at creating a plane. Blaise Pascal's Mechanical calculator. Prototype metre bar. Old supercomputers...

They also have Foucoult's pendulum (the original, as well a working replica in action). It's a really unique feeling to observe the earth rotating beneath you.

I loved this museum when I visited. I learned about here on Hacker News, so I hope others will take note of this museum. It was remarkable how beautifully designed the objects were. Scientific instruments, architectural models, prototypes and machinery. All beautifully made with a focus on aesthetics as well as functionality.

I can't read about the Musée des arts et métiers without thinking in Umberto Eco's book (Foucault's Pendulum)

If you pass in Milan you should not miss the "museo nazionale della scienza e tecnologia leonardo da vinci"[0], filled with labs, expositions ... and a real submarine (the S506 Enrico Toti)
