The roof of the central quadrangle in the British Museum proves that modern architecture can still be classy.

Here’s a section of another old building, The British Museum, which has been retrofitted with modern glass. The central quadrangle of the museum was redesigned with this glass ceiling, and each section needed to be a different shape in order to accommodate the roof’s waves. In all, there are 1,656 pairs of windowpanes. One imagines that putting them up might have been similar to assembling a gigantic jigsaw puzzle.
