Piazza Fontana fountain, Historic fountain in Piazza Fontana, Milan, Italy.

The Piermarini Fountain is a neoclassical fountain in pink Baveno granite, covering 20 square metres. It has three stacked basins of different sizes: water drips from the top basin into the middle one, where two dolphins carry two sirens, then falls into the lower main basin and out through four spouts into ground-level basins. The two marble sirens, by sculptor Giuseppe Franchi, were added the year after the 1782 inauguration.

The fountain was commissioned by Carlo Giuseppe di Firmian, Maria Theresa of Austria's plenipotentiary, from architect Giuseppe Piermarini during work on the square. It was inaugurated on 15 August 1782 after 13 years of construction, still unfinished: the marble sirens by sculptor Giuseppe Franchi were only installed the following year. Water had to be brought from the Seveso river, and the insufficient slope forced Piermarini to lower the structure below the square's level and place a pump at Via delle Ore.

Locals nicknamed the two marble statues "Teodolinde", and the fountain gave its name to the surrounding piazza. The sirens were not ready at the 1782 inauguration and were placed only the following year. The work was commissioned by Carlo Giuseppe di Firmian, plenipotentiary of Maria Theresa of Austria.

The fountain sits on Piazza Fontana in the heart of downtown and is easily reached on foot. You can visit at any time of day since the water feature operates continuously.

The two marble statues of dolphins ridden by sirens, carved by Giuseppe Franchi, were not ready at the inauguration on 15 August 1782 and were only put in place the following year. Milanese nicknamed them "Teodolinde".
