In 1851, physicist [[Léon Foucault]] demonstrated the rotation of the Earth by constructing a {{convert|67|m|ft|adj=mid}} pendulum beneath the central dome. The original sphere from the pendulum was temporarily displayed at the Panthéon in the 1990s (starting in 1995) during renovations at the [[Musée des Arts et Métiers]]. The original pendulum was later returned to the [[Musée des Arts et Métiers]], and a copy is now displayed at the Panthéon.<ref>{{cite web |url=http://itotd.com/articles/362/foucaults-pendulum/ |title=Foucault's Pendulum: Interesting Thing of the Day |publisher=Itotd.com |date=2004-11-08 |access-date=2014-02-21 |archive-date=2012-03-12 |archive-url=https://web.archive.org/web/20120312175754/http://itotd.com/articles/362/foucaults-pendulum/ |url-status=dead }}</ref> It has been listed since 1920 as a ''[[monument historique]]'' by the [[Ministry of Culture (France)|French Ministry of Culture]].<ref name="merimee">{{Base Mérimée|PA00088420}} Ancienne église Sainte-Geneviève, devenue Le Panthéon</ref>
