Berlin Modern Museum Delayed Again as Moisture Damage Pushes Opening to 2030

Berlin's long-awaited Berlin Modern museum has been delayed again, with its opening now pushed to 2030 due to moisture damage in the building's shell and microbial contamination in other parts of the structure. The Prussian Cultural Heritage Foundation announced the delay after the Berlin-Brandenburg Broadcasting Corporation broke the story. The Herzog & de Meuron-designed building, originally scheduled to open this year as the Museum of the 20th Century, has faced multiple setbacks since groundbreaking in December 2019, with completion dates slipping from 2026 to 2028, then 2029, and now 2030. The project's cost has ballooned from €200 million to €507 million.

The completion of Berlin Modern, a major new museum in Berlin, has been delayed again until 2030 due to moisture damage and microbial infestation found in parts of the raw structure. The Stiftung Preußischer Kulturbesitz (SPK) announced an estimated eight-month postponement, though no construction stop was required. The museum, designed by Herzog & de Meuron, is being built near Potsdamer Platz to expand the Neue Nationalgalerie's exhibition space. Costs have risen from an initial €200 million to a projected €507 million.

Opening of Berlin Modern postponed to 2030

The opening of the Berlin Modern museum has been delayed to 2030 due to construction setbacks and cost overruns. According to German media outlet Monopol, the project has been plagued by humidity issues, including mold, algae, and bacteria on new surfaces, caused by winter dampness, concrete sensitivity, and faulty ventilation. Originally launched in 2019 with a planned opening in mid-2020, the museum's completion has been repeatedly pushed back, with costs soaring from an initial €200 million to over €500 million, making it the most expensive museum ever built in Germany. The building, designed by Swiss firm Herzog & de Meuron, is located at the Kulturforum and will house 20th-century art collections from the Nationalgalerie, the Marx Collection, the Pietzsch Collection, and holdings from the Kupferstichkabinett and the Kunstbibliothek.
