Humboldt Forum, Berlin


Cultural connections

The location of the Humboldt Forum in Berlin is steeped in history. Recently put together by Italian architect Franco Stella, the crucial aspect was the fusion of old and new elements. The museum’s access areas and entrances experienced particularly heavy loads, which SIMONSWERK is able to effectively support using hinges from the VARIANT VX series, among other solutions.
