Photo, above: The Green Cathedral is in Italy on the slopes of the Arera mountain near the northern city of Bergamo. It was designed by Giuliano Mauri, a natural architect who died in May 2009. It stands 21 metres tall, with five aisles and 42 columns. It's 28.5 metres long and 24 metres wide, built from 1800 firs, 600 chestnut branches and 6000 metres of hazel branch that's been woven into the design. Forty-two beeches have been planted inside, which will grow over time to provide the roof to the structure, which remains open to the rain for the time being.  See: Hour 2, Turing's Cathedral: The Origins of the Digital Universe (Vintage) by George Dyson
