Fontana del Viminale, Drinking fountain in Piazza del Viminale, Rome.

Fontana del Viminale is a fountain on Piazza del Viminale in Rome, set about half a metre below street level in a rectangular sunken area with semicircular bulges on its short sides. A rectangular pool holds a large rectangular base carved with the three heraldic mountains of the rione, the Capitoline Wolf and a turreted crown; two supports carry a shallow rectangular basin with two spherical elements from which water spouts.

The fountain was designed in 1929 by architect Publio Morbiducci from a project initially planned for Piazza Mastro Giorgio in the Testaccio district. The design was adapted and eventually placed at its current location.

The long sides of the fountain's rectangular base carry low reliefs: the three heraldic mountains of the rione Monti, the Capitoline Wolf, and a turreted crown standing for Italy. The basin above is framed by two pairs of imitation handles. The last restoration of the fountain was in 1999.

The fountain sits in a sunken rectangular pool about half a metre below street level, reached by three steps at the centre of each long side. A railing on twenty stone posts runs around the perimeter, so the basin is viewed from above rather than approached directly. The square lies between the circular ramps leading to the Interior Ministry entrance.

The fountain was first designed for a competition for a square in Testaccio. Publio Morbiducci did not win, but the committee awarded him a cash prize and ruled that his fountain deserved to be built anyway. In 1929 he was instead commissioned to furnish the square in front of the Palazzo del Viminale.
