Louvre Museum

Louvre Museum (ルーブル美術館) is one of the largest museums in the world. It is located in Paris, France and it is one of its central landmarks.

Stiyl Magnus of Necessarius mentions that Index has been to the museum prior to the start of the first volume in the timeline alongside the Vatican Library, the Pataliputra ruins, Château de Compiègne, and Mont Saint-Michel Abbey. There is apparently a grimoire or more sealed in the museum which cannot be taken away.
