Giant Fake Waterfall!!

Hey all, so today we went to a 2000 year old man-made (Roman) Waterfall. They built it to irrigate the surrounding Terni farmland and it is HUGE. It doesn't look fake at all, in fact I got close to it through this cave and got a little (a lot) wet. It is really bizarre to me that the Romans just decided to build a waterfall of this scale just because they could; very impressive. There is actually a valve that turns this thing off, weird right? I don't have any pictures because I forgot my camera, but I am sure someone will post for your viewing pleasure. Later all.
