PARIS (AP) — Employees at the Louvre Museum voted to extend a strike that has disrupted operations at the world’s most visited museum, though the attraction partially opened Wednesday to allow visitors to enjoy the “Mona Lisa" and other highlights.

The museum said that visitors have started entering the building, where they had access to a limited “masterpiece route” which includes Leonardo da Vinci’s “Mona Lisa” and the famous Venus de Milo.

“Due to a strike, some rooms in the Louvre Museum are ... closed," it said on social media. “We apologize for any inconvenience.”

Union workers are protesting chronic understaffing, building deterioration and recent management decisions — pressures intensified by a brazen crown jewels heist in October.

The decision came during a morning general assembly, after workers had adopted the walkout unanimously earlier this week. The museum was shuttered Tuesday for its weekly closed day.

Tensions have been further sharpened by fallout from the theft of crown jewels during a daylight robbery that exposed serious security lapses at the museum.

Culture Ministry officials held crisis talks with unions Monday and proposed to cancel a planned $6.7 million cut in 2026 funding, open new recruitment for gallery guards and visitor services and increase staff compensation. Union officials said the measures fell short.

Louvre President Laurence des Cars was scheduled to appear before the Senate’s culture committee later Wednesday as lawmakers continue probing security failures at the museum.

Des Cars has acknowledged an “institutional failure” following the heist but has come under renewed scrutiny after admitting she only learned of a critical 2019 security audit after the robbery. France’s Court of Auditors and a separate administrative inquiry have since criticized delays in implementing a long-promised security overhaul.

The Culture Ministry announced emergency anti-intrusion measures last month and assigned Philippe Jost, who oversaw the Notre Dame restoration, to help reorganize the museum. The move was widely seen as a sign of mounting pressure on Louvre leadership.
