Never a dull moment. Paris masters the art of renovating and innovating its old buildings all while enhancing their original splendor and grandeur. Here are 4 recently opened examples and must-sees: The renewed Musée Carnavalet right in Le Marais, about the history of the city of Paris; La Bourse Commerce where business tycoon, art collector and mecenas François Pinault brings together the blue-chip artist of our times in his opening exhibition titled Ouverture; the totally renovated  Art Nouveau store or rather shopping paradise La Samaritaine, and the historic l’Hotel de la Marine overlooking the Place de la Concorde. Enjoy!
