While the rest of the world takes the train out to Versailles, take a day trip from Paris in the other direction and visit the famous Villa Savoye à Poissy, designed by none other than Le Corbusier. The purist style, modular house shows the designer's later influences and looks different from every angle. After WWII the house had fallen into disrepair, but has since been restored and opened as a national monument. --Toni Kervina
