The colossus with feet of clay: when the Senate sounds the alarm on the technical decline of the BnF
Barely thirty years after the inauguration of the François-Mitterrand site, the colossus of Tolbiac is teetering under the weight of obsolescence.
1. Modern architecture standing the test of time: the Senate’s “critical” diagnosis
There are monuments that carry within them the ambition of a century.
A glass palace dependent on invisible machinery
Contemporary architecture suffers from a singular evil: its absolute dependence on an invisible and cyclical technicity.
Technical “self-cannibalism”: surviving in an emergency
However, analysis tools reveal that 25% of this equipment is already in a “very critical” state, and 30% in a “critical” state.
2. The invisible peril: the major risks for national heritage
The issue goes beyond simple routine maintenance;
The climate challenge and the greenhouse effect of the four towers
Designed at a time when the Ile-de-France climate ignored repeated heatwaves, the four monumental glass roofs by architect Dominique Perrault today act as thermal greenhouses.
Threat to legal deposit and fire safety
The risk is none other than the withering away of a national treasure or the paralysis of this mecca of French research.
3. Facing the “investment wall”: recommendations from the wise
Faced with this “investment wall”, the Senate calls for an imperative fiscal and management boost.
A half-billion euro plan to save Tolbiac
The overall requirements for a complete renovation are now estimated at a staggering €527.6 million, including an accumulated maintenance debt of €88 million.
Recomposing heritage: from Amiens to Arsenal
At the same time, the report draws the outlines of a necessary recomposition of the overall heritage of the BnF.
Conclusion: Substitute foresight for urgency for the dignity of our heritage
It is part of the dignity of our Republic to face the failures of its modern temples.
