Rue de Rivoli (Paris)
This is a very unusual view, from the top of the nearby Tour Saint-Jacques (a medieval tower that is off-limit, no trespassing and permanently closed to the public). The photo was taken at night using long exposure.
The camera is facing the North-West direction. The Rue de Rivoli is the one going from the bottom-center to the top-left of the image. The street going to the center-right is the Boulevard de Sébastopol. The street branching off from rue de Rivoli and going up toward the center-top is the Rue des Halles. In the upper-right of the photo you can clearly see the Église Saint-Eustache and the hill of Montmartre in the distance.
