Not only that autumn is my favorite season weather wise, but also every September takes place my most anticipated weekend of the year; the European Heritage Days (Les Journées du Patrimoine). During these two- or three days most of the monuments, government buildings and cultural sites, even the ones that are usually closed for public, open their doors for free visits.

This time I went to visit the Préfecture des Hauts-de-Seine in Nanterre, which sounds nothing but boring for anyone who lives in Paris. But what an overly 70’s, gorgeous design- and art heaven it was behind closed doors. I especially loved the LC1 chairs by Le Corbusier and Charlotte Perriand, which were everywhere down the halls and conference rooms.
