Cloaca Maxima
The Cloaca Maxima is a major ancient Roman drainage tunnel visible where it opens to the Tiber river as a large arched mouth set into the riverbank. Substantial ashlar masonry and rounded buttresses remain at the river edge and a paved ledge sits beneath the arch. Portions of the tunnel and riverfront embankment are accessible to pedestrians today.

As it stood in AD 1
What Cloaca Maxima looked like in its prime.
A single, wide semicircular stone arch set into a high riverside retaining wall opens over the Tiber; courses of pale ashlar blocks form the arch and flanking buttresses with stepped curved cutwaters. A narrow paved ledge runs under the arch at water level. Above, a roadway and metal balustrade continue along the riverbank; behind the wall a line of stone columns and trees can be seen. Surfaces show water staining, lichen and weathering but the masonry is largely continuous.
