The Fontana Pretoria fills the centre of Piazza Pretoria, a sequence of concentric basins crowded with marble figures of river gods, allegorical women, satyrs, putti, and animals. Sixteen statues stand on the lowest level, with smaller groups rising in tiers up the central column. By Francesco Camilliani and Michelangelo Naccherino, finished 1554.
The piazza is closed to traffic and the fountain is illuminated at night. The neighbouring church of Santa Caterina d'Alessandria, with one of the most ornate Baroque interiors in the city, is worth combining with the fountain visit.
