The fountain, designed by Muñoz and inaugurated in 1933, is part of the wider arrangement of the area, characterised by the Municipal Antiquarium (reopened in 1929) and the widening of the road - then called Via dei Trionfi, today Via di S. Gregorio - from the Arch of Constantine to Piazzale di Porta Capena, provided for in the town plan of 1931.
Author: Antonio Muñoz.
Date: 1933.
Materials: white marble, serpentine, travertine, peperino.
Inserted in the retaining wall of the Antiquarium, on the slopes of the Caelian Hill, in correspondence with the fountain above it, the fountain is framed by two massive brick propylaeums; the vertical part consists of a marble 'portcullis' structure, over which the water flows with a cascade effect. The water flows into the rectangular serpentine basin with indentations on both sides. The surface is formed by three travertine steps, bordered at the corners by travertine columns. On the back wall, characterised by smooth peperino ashlars, there are two marble tables at the sides of the waterfall, originally decorated with fasces lictors (later chiselled away) and the inscription S.P.Q.R. in capital letters in relief. The general composition of the space is inspired by northern European fountains known to Muñoz.
