Can you drive by something for 20 years, and not be aware of the wonders just few meters from the road? You can. I had not heard about the Bemböle watermill ruins.
I was looking through the Internet to find interesting places to visit nearby. Ruins, caves... and found a story about the the Bemböle watermill. I had some trouble locating the place, as the descriptions were a bit cryptic, and the Ring III intersection that it was next to spans a large area.
I had no idea about the ruins being right next to a highway ramp I take almost daily. They are literally twenty meters away from the ramp, but hidden from view by trees and bushes. In fact, I did not even realise there is a river or rapids there. Or even that the ground drops into a valley under all the vegetation.
