Designed by Nicola Salvi and completed by Giuseppe Pannini, the Trevi Fountain terminates the Aqua Virgo with a cliff‑like façade and Oceanus at center. Frequent cleanings and biofilm control preserve travertine figures against urban pollution. Ritual coin tosses fund charity; visitor caps and policing mitigate crowding in Rome’s tight streets.
The fountain formalizes the ancient Aqua Virgo terminus. A triumphal arch composition frames a rocky proscenium; niches host allegories of Abundance and Salubrity.
Travertine blocks are carved to evoke grotto and cascade; hydraulics choreograph multiple jets and sheets. Adjacent palazzi provide viewing balconies.
Travertine’s porosity invites biofilm; gentle biocides, poultices, and micro‑consolidants are cycled. Fencing and frequent patrols manage the piazza’s dense flows.
Pre‑dawn or late night reveal the fountain with fewer crowds and dramatic lighting.
