Lecture by Christopher Alexander at the Graduate School of Design, Harvard University: Visual material used in the lecture for illustrating his points
9 5th pair – The plan of Alhambra paired with the Renaissance Center plan, Detroit

Pairs of photographs mostly of buildings, used by Christopher Alexander in the lecture, each one comparing side-by-side one contemporary building with a building from the past, in order to argue the point that the “works of our time simply do not belong to that family of things buildings that I’ ve just shown” –using his own words. He showed eleven examples of pairs, but the archive inludes the photographs of the following first five pairs, and one of the photographs of the last two pairs. .
