One of the first duties of the Stiftung was the maintenance and renovation of the remaining buildings in accordance with the laws concerning the preservation of historical monuments. The most important parts of the concentration camp were to be restored as places of historical importance and as a testament to the camp's existence.
An important part of the new planning of Sachsenhausen is its decentralised concept, which brings the history of the site to life in an authentic setting. Thirteen exhibitions tell the story of Sachsenhausen exactly where the events occurred and are all linked to the central idea while focusing on one particular point of history. In 1995 the architects 'Braun & Vogt' put forward their plans for the site and these were unanimously accepted by all committees belonging to the Stiftung. In 1996 the committees decided on a provisional investment plan which defined and prioritised the various projects. During the first 10 years of the Stiftung €16,4 million has been invested in the renovation of Sachsenhausen. The funds have been provided by the county of Brandenburg and the federal government.
Seven of the 13 planned permanent exhibitions have already been opened and two more are due to open in 2004 - 'the town and the camp' in Tower E on 10 October and 'medicine and crime' in the original barracks of the infirmary on 7 November.
By 2006 the redevelopment should almost be completed. Sachsenhausen memorial and museum will still be a place of mourning and remembrance but it will also be able to face up to the challenges of a modern historical museum.
