Louvre employees closed the Paris museum on Monday, protesting working conditions and other grievances.
Labour leaders said 400 staff voted unanimously to strike for the day.
Strikers blocked the iconic glass pyramid with flags, banners, and placards.
The Louvre posted an update online, confirming an exceptional closure and promising refunds to ticket holders.
Officials did not immediately clarify whether the strike would extend beyond one day.
The museum normally closes on Tuesdays, giving staff time to meet again Wednesday to decide next steps.
Visitors express frustration and understanding
Tourists arriving at the museum faced disappointment and frustration.
Lindsey Hall, from Sacramento, California, said she had eagerly planned to explore the Louvre with a friend.
She described the collection as “epic” and a life experience everyone should see.
Hall also said she understood the daily challenges faced by museum workers.
Security concerns and staffing shortages spark anger
The strike followed last week’s talks between unions and Culture Minister Rachida Dati.
Union leaders said discussions failed to address staffing and budget concerns at the busy museum.
CFDT’s Alexis Fritche called visiting the Louvre “an obstacle course” due to overcrowding and staff shortages.
Staff cited the October jewellery heist as proof that thin staffing and poor security threaten the museum.
Police later arrested four suspects accused of stealing €88 million in crown jewels.
Investigators blamed outdated cameras, understaffed control rooms, and poor coordination for the heist’s success.
Unions demanded more security personnel, improved working conditions, and stable budgets.
CGT’s Yvan Navarro said rising visitor numbers clash with stagnant staff levels and salaries.
Union notices described the Louvre as in “crisis” with deteriorating conditions.
The Culture Ministry appointed Philippe Jost to propose a major reorganisation.
Jost previously managed Notre Dame’s reconstruction after the 2019 fire.
He will work with Louvre director Laurence des Cars and submit recommendations by late February.
Des Cars described the October heist as a “terrible failure.”
