Notre-Dame : pas de suspension pour les vitraux !

On May 19, 2026, the Paris administrative court rejected requests from heritage associations Sites & Monuments and SOS Paris to suspend the removal and replacement of the stained-glass windows at Notre-Dame Cathedral. The associations had sought to block the prefect's authorization to remove the 19th-century windows by Alfred Gérente and install six new contemporary windows designed by Claire Tabouret, arguing legal doubts about the project. The judge ruled that the operation was reversible—since the new panels are the same size as the originals and the removed windows will be restored and displayed—thus no urgent suspension was warranted.

No money, more problems: 85% of US museums in urgent need of building repairs

A recent survey by the US Government Accountability Office (GAO) found that approximately 85% of US museums face a costly backlog of maintenance or building repairs, with 77% having at least one structural issue that puts their collections at risk. Based on a survey of around 300 museums and 17 site visits, the report reveals that institutions across the country struggle to keep buildings updated and safe due to a lack of funding, with challenges especially pronounced in rural and remote locations where shipping materials and finding skilled workers is prohibitively expensive. Many museums are housed in historic homes or sites that are part of their collections, adding further complexity, and smaller museums often lack the budget to address major problems like new roofs or HVAC systems.

What the renovation of the Pergamon Museum costs

Was die Sanierung des Pergamonmuseums kostet

The Pergamon Museum in Berlin is undergoing a major renovation with a total budget of €1.5 billion for both construction phases, including cost risks. The Federal Office for Building and Regional Planning (BBR) has announced that current projections indicate the overall costs will not be exceeded. Phase A, which includes the hall housing the famous Pergamon Altar, is expected to open on June 4, 2027, with a potential cost increase of up to 5% over the originally approved €489 million. Phase B, covering the Ishtar Gate and Babylonian Processional Way, has seen its cost forecast reduced by €27 million to €722.4 million, with an additional €295.6 million set aside for risks and price increases. The museum will fully reopen only in 2037.
