"Cloaca Maxima is often mentioned in history books and yet it's nearly impossible to find sites related to it. This unmarked arch at Tiber 's embankment is supposedly the place where it coonects to the Tiber river. Here, among homeless people encampment you can actualy see a small sewage outlet. Does it mean that the ancient sewage system is still working, buried under Rome's streets? If so, I would love to learn more about it current state, better yet - tour it.
btw
nearby, behind the Arch of Janus, is a place that seems to be connected to Cloaca Maxima (see photos)"
