The Berlin Series,

The modern architectural elements of the Libeskind building comprise the zinc façade, the Garden of Exile, the three Axes of the German-Jewish experience, and the Voids. Together these pieces form a visual and spatial language rich with history and symbolism. They not only house the museum with its exhibits, but they also provide visitors with their own unique experience as they walk through the spaces.
          ( I cut an paste the above so I should give them credit but I can't find it; thanks, sorry:)
