Three weeks after the spectacular jewel theft at the Louvre, the museum has been heavily criticised for neglecting security.
The Court of Auditors report, drawn up before the heist, found that for years managers had preferred to invest in new artworks and exhibitions rather than basic upkeep and protection.
"Let no-one be mistaken: the theft of the crown jewels is a resounding wake-up call," said the court's president, Pierre Moscovici.
In broad daylight on Sunday 19 October, thieves broke into the Louvre's first-floor Apollo Gallery. Using a angle-grinder to open display cases, the gang made off with €88m (£78m) of jewels that once belonged to 19th-Century queens and empresses.
Basing its findings on the years 2018 to 2024, the report says the Louvre "favoured operations that were visible and attractive at the expense of maintenance and renovation of technical installations, notably in the fields of safety and security".
In the period studied, it found the museum spent €105.4m on buying new artworks and €63.5m on exhibition spaces.
But at the same time it spent only €26.7m on maintenance works and €59.5m on restoration of the palace building.
