Which planet or star is this? The picture was taken with a smartphone camera at Latitude 48.860045 | Longitude: 2.366202 the 31th of July at 01h07min15s Paris time. On the left is obviously the Moon, and the lower red circle points the point of Latitude: 48.852886 | Longitude: 2.369167. (It's the angel of liberty, place de la Bastille, Paris.)

What does the upper circle point to ?

At the beginning I thought it was Venus, but as far as I remember, it disappears quite early in the evening. I don't think it is Mars : the light reflection on it isn't red enough.
I think it is Mars.  Although it's difficult to tell, just looking at the image, but if it were Saturn then you would also be able to see Mars.  Mars is much brighter than Saturn at the moment, so if Saturn were visible, Mars would be even brighter.  The fact that there is only one bright object (other than the moon) is, I think, conclusive evidence that this must be Mars.

Looking over the city, the large brick building on the Rue St Gille is visible, and the object is visible directly in line with the phone mast on that building. That gives a direction just East of South. Checking with Stellarium at the given time shows Mars at exactly that position, at an azimuth of 171.
