Alexandre III bridge and the invalides in paris

Last year, I went once there, the lights were off, I went a second time, still off, I called the city hall in order to know when the lights will be on again, they told me that everything was working; so I went again and each time the lights were off. Then covid and "couvrefeu" so I couldn't go there at night. Finally, last Sunday I saw the students partying in the garden on the other side of the bridge, the police charging to kick them off the garden and in the background I saw the lights on! So I came back yesterday and finally get the pictures with the light of the bridge!
