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.

This update matters because the Pergamon Museum is one of Germany's most visited cultural institutions and a key part of Berlin's UNESCO World Heritage Museum Island. The €1.5 billion renovation is one of the largest museum construction projects in Europe, and staying within budget is a significant achievement given widespread cost overruns in major public infrastructure projects. The phased reopening allows the public to access the Pergamon Altar again from 2027, while the complete restoration of the entire museum—including the iconic Ishtar Gate—will take another decade, highlighting the long-term commitment to preserving world heritage.
