The Louvre, the world’s most-visited museum and a global symbol of art, beauty and endurance, remained shuttered Monday — not by war, not by terror, but by its own exhausted staff, who say the institution is crumbling from within.

In the wake of that growing movement, workers at the Louvre reportedly spontaneously decided to walk out during a standard staff meeting on Monday, per the AP. Gallery attendants, ticket takers, and security all refused to operate their posts, complaining that the crowds have become unmanageable and the museum is understaffed.
