Photos of ruins and structures from past eras

What is a ruin? We're running off of "You know it when you see it" at the moment. Ruins should be non-functioning structures of some age, or their function reduced to tourism and the like. Generally speaking, specific items from a ruin should go to [email protected] Illustrations of ruins (or their reconstructions) should go to [email protected] Photos of ruins back when they were functioning should go to [email protected]

Any idea what these would have powered? Grain mills?

Edit: I think it's this one:

That’s cool.

Probably a dumb question, but physics was never my strongest subject…. But would the mill at the top have more or less power (torque?) than the one at the bottom?

Probably? I think? Because of the momentum of the water at the top, and the loss from friction each 'step' down past the waterwheels?

But my understanding of physics is pretty barebones lmao.

Assuming the water is still (lake etc) at the top, they will have the same power. The energy you get from the water is the height times weight, and since each mill has the same height for water to fall, they will produce the same.

If you removed all the ones in the middle, then the bottom one would have more power than the top one as the water would fall from higher up building up speed.
