This picture was taken this summer in the south of France, in case it’s relevant. The area was on the side of a mountain (near a village) and had olive trees all around. Any idea?
I couldn’t get close to measure it since it was down below the “trail” I was walking on, but from what I remember it was big but not very big, maybe about as large as the space between my feet when I stand with my legs spread wide? I’m not very sure, but when I look for pictures of grain silos, they seem way bigger. (Yes, I needed to google “grain silo”, I’m a city girl.)
