Fontana della Pigna, Renaissance fountain in Piazza Cavour, Rimini, Italy.

The Fontana della Pigna is a fountain on Piazza Cavour featuring a large pine cone sculpture as its centerpiece. The structure displays decorated stone carvings with patterns from the Roman period and has been reworked several times.

The fountain dates from the Roman era, fed by a conduit from a well about 900 m away. In 1540 fireworks placed in the basin to honour Cardinal Giovanni Maria Ciocchi del Monte damaged it; Pope Paul III funded a complete rebuilding by Giovanni da Carrara in 1543, reusing stone fragments while keeping the Roman central drum. A statue of Saint Paul was added in 1545, replaced by the pine cone after French troops damaged the fountain and stole its bronze spouts during the Napoleonic period, leading to a restoration in 1807.

The pine cone on top replaced a statue of Saint Paul in 1807, during a restoration after French troops damaged the fountain and stole its bronze spouts. Commemorative plaques on the drums record the 1543 rebuilding funded by Pope Paul III. One panel carries Leonardo da Vinci's words from his visit on 5 August 1502, noting the harmony made by the falling water.

The fountain is located on a main plaza and is easily reached by walking from the town center. The best time to visit is early in the day when sunlight clearly illuminates the details of the carved stonework.

On one panel of the fountain Leonardo da Vinci had engraved the phrase he spoke during his visit to Rimini on 5 August 1502, struck by the harmony of the jets: "Fassi un'armonia con le diverse cadute d'acqua, come vedesti alla fonte di Rimini". The water came from a well about 900 m away, first through a stone conduit later replaced by cast iron.
