Piazza Duomo con Fontana del Nettuno

Trento's Piazza Duomo brings together the cathedral of San Vigilio, Palazzo Pretorio, the Civic Tower and painted historic houses. At its centre, the Neptune Fountain adds eighteenth-century theatricality to the square's medieval and Renaissance setting.

Why it matters

The fountain was both a civic ornament and a water-supply project. Its architecture expressed public ambition while bringing clean water into the city centre.

What to notice

Red Trento stone forms the stepped base, basins and central structure. Tritons, sea horses and putti riding dolphins animate the composition. The Neptune above the upper basin is a twentieth-century bronze replacement; Stefano Salterio's original stone statue survives at Palazzo Thun. Painted facades around the square add another layer of colour.

Context and history

The civic magistracy commissioned Francesco Antonio Giongo to design and build the fountain in 1767. It was inaugurated in June 1769 for the feast of San Vigilio. Andrea Malfatti renewed the sculptural groups in 1869–1872. The possible connection between Neptune's trident and the Roman name Tridentum remains a suggested explanation for the subject.
