The ponds of Nanatsudo Park are joined by five dams, ‘Dam A’ through ‘Dam E’, designed in a variety of styles to illustrate the progress of time, from ancient to modern times, in a downstream sequence.
‘Dam C’, an embankment structure called an earth dam, employs civil engineering technology.
At the end of Dam C is the ‘Fountain’ (wall fountain).
In ancient Rome, fountains such as these formed the terminal points of Roman aqueducts.
The famous Trevi Fountain, which itself originally served as the terminus of an aqueduct, has been recreated on the present site.
