Conversion of the North Gate Building and the Orangery in the Sanssouci Palace Park, Germany. The valuable, 250-year-old historic fabric of the buildings, part of the UNESCO World Heritage Site, was preserved as far as possible and carefully restored in a manner appropriate to the monument. It houses the first academic education center for rabbis and cantors in Central Europe after the Shoah. Potsdam's first synagogue is located in the center of the listed ensemble. The original use of the Orangery should be recognizable again by getting back the typical character with contemporary means.
