A museum containing artifacts both ancient and modern of the Arab world, the Institut du Monde Arabe is not only interesting to explore but also simply to look at. The exterior of the building consists of light-sensitive windows that open or close to modulate the amount of lighting within the building. We saw the exhibit “L’âge d’or des sciences arabes” which portrays the development of science, math, and engineering from the middle ages through modern times in the Arab world.
