Leaky Berlin Modern Museum’s Opening Delayed Until 2030

The opening of the Berlin Modern Museum, a planned extension of the Neue Nationalgalerie, has been delayed until 2030 due to significant moisture damage and microbial contamination in its foundation, floors, roof coverings, and exterior walls. Originally laid in February 2024 with a projected 2027 opening, the museum's construction costs have surged from 200 million to 507 million euros, according to Monopol. A spokesperson for the Prussian Cultural Heritage Foundation stated that repairs are underway but will push completion back by approximately eight months.

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 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.
