Pergamon Museum renovation costs and timeline spiral, troubling German government

cultural-heritage · 2026-04-26

The Pergamon Museum on Berlin's Museum Island, closed since October 2023, faces escalating costs and delays. Originally estimated at €250 million, the renovation now exceeds €1.5 billion, with full reopening pushed from 2037 to possibly 2043. The project, part of the Masterplan Museumsinsel Berlin initiated under Chancellor Gerhard Schröder and led by David Chipperfield's firm, includes a new wing, connections to the Bode and Neues Museums, and a bridge. Der Spiegel reports underground cavities, contractor disputes, and tensions between the Federal Office for Building and Regional Planning and the Prussian Cultural Heritage Foundation are hampering progress. Partial reopening for the Pergamon Altar is expected in 2027.
