Louvre

One universe's version of Jenny Everywhere and her master-thief lover and accomplice once attempted to steal a huge diamond (COMIC: My Bloody Valentine) from the Louvre. (PROSE: Morning After)

In the 925th Universe, Stardust the Super-Wizard once foiled a robbery at the Louvre via the somewhat heavy-handed method of deleting France in its entirety. (PROSE: A Series of Queer Events)

In some unspecified universe it apparently housed Leonardo Da Vinci's painting Mona Ovunque, prints of which were available in the gift shop.
