Imperial War Museum North

War museums generally appeal to those with a fascination for military hardware and battle strategy, but Daniel Libeskind's visually stunning Imperial War Museum North takes a radically different approach. War is hell, it tells us, but it's a hell we revisit with tragic regularity. Although the audiovisuals and displays are quite compelling, the extraordinary aluminium-clad building itself is a huge part of the attraction, and the exhibition spaces are genuinely breathtaking. Libeskind designed three separate-but-linked structures, or shards, that represent the three main theatres of war: air, land and sea.
