Personally, I think that museums are not necessarily only officially recognised institutions. Wealthy families of the XVI/XVII centuries liked to have their own wunderkammers. Today we all like the open air attractions. This is something you see during a road trip, and it makes you stop and reflect, then take a picture or selfie.
You are welcome 🙂
