This is quite outdated subject. I visited Paris in Feb 2011 the second time for a-week-long Hazard and Operability Study (HAZOP) for Plateau Maintenance Project, conducted at Technip Office in La Defense. Unlike last year summer visit, this was during winter when temperature was still freezing (1-5 C) and rain was a daily guest.
Not many places visited this time as many have been covered during my summer visit. I managed to climb up Tour Montparnasse that offers 360 deg panoramic view of Paris from above, took shots of Musee du Louvre during the night, strolled around Hotel de Ville, then guided my colleague to visit Notre Dame and Basilique Sacre Coeur.
Enjoy some of my shots.
