First of all, thank you for all your comments. I could not enter the building since it was a private one. That's why I had to take the shots behind the railings. Sorry for this.
After reading all the comments, my thoughts about that the plant could be artificial is: Could be possible, but I see that the fruits (or whatever they are) are so arbitrary distributed. On an artificial product, I believe that all the fruits would be positioned mostly in front of our eyes. I see also some almost touching the ground. (See the last pic I have uploaded). In addition to that, I see different sizes and color variations of these fruits. Would an artificial product embody such color and size variations?
About the seam; looks to me more like a thick spider web.
I will try to visit that street this week again and try to find someone to ask about it. If this is something artificial, I will inform you as well. If this is not artificial,
I am curious what it is :)
Thank you all for your considerations.
