Moritzburg in Halle is among the most impressive castles built in central Germany in the late middle ages. Originally the sumptuous seat of Magdeburg’s archbishops, it was reduced to rubble during the Thirty Years’ War. Over the ages, a variety of functions and styles have been foisted on the castle. Since 1904, the municipal museum of arts and crafts has been housed in the south and east wings. The ruins on the north and west were made fit for occupation again to provide much-needed additional exhibition space. An aluminium-clad roof, articulated by skylights rising and falling irregularly in response to the extant, non-uni-form structures, tops off the historic shell. It appears to hover above the old walls.
