Near the Balard Metro station, the French Ministry of Defence is putting the finishing touches to its new HQ, dubbed the French Pentagon. The construction site punctuates the skyline, offering glimpses of shiny new buildings behind high fences, a panorama that we are forbidden to photograph.
Sitting opposite on the other side of the Boulevard Victor, separated by the neat green carpet of the tramway, is another building that is almost military in form. Around 50 metres long - but only 10 metres wide at its broadest point (barely more than 2 metres at its narrowest) - this nautical looking structure though has no connection to its combative neighbour. This is perhaps architect Pierre Patout's finest moment, and a piece of design history that you could today own - if you have €2 million to spare.
