Rome's fountains are not decoration — they are the endpoints of an aqueduct system that has supplied the city continuously for 2,000 years. Here is the complete guide.
Plan my Italy trip →The Trevi Fountain runs on the same aqueduct Marcus Agrippa built in 19 BC. The 2,500 Nasoni street drinking fountains that Romans use daily draw from the same water system. Rome is the only major world city where ancient water engineering still provides daily drinking water to its residents — the continuous operation of the Aqua Virgo from 19 BC to the present is one of the most extraordinary engineering legacies in human history.
The Fontana di Trevi (Piazza di Trevi) is Rome's most famous fountain and largest Baroque fountain — 26 metres high, 49 metres wide, carved from travertine and using approximately 80,000 cubic metres of water per day. The designer: Nicola Salvi, who won the design competition in 1730 and worked on it until his death in 1751; the fountain was completed by Pietro Bracci in 1762. The mythological subject: Neptune (Oceanus) standing in a shell chariot drawn by winged horses (hippocamps), flanked by Tritons — the left triton calms a rearing horse (rough seas), the right triton controls a docile one (calm seas). The coin tradition: throwing a coin backward over the shoulder is documented from at least the 1950s (the film Three Coins in the Fountain popularized it internationally in 1954, though the tradition is older); approximately €1.5 million in coins are collected annually from the fountain basin and donated to a Rome Catholic charity (Caritas). Best visiting time: between midnight and 6am when the piazza is as clear as it ever gets (the fountain is illuminated). The dawn light at 6:30am on a summer morning with fewer than 30 people present is the Trevi Fountain at its finest. By 10am there are typically 300+ people in the small piazza.
The Fontana dei Quattro Fiumi (Fountain of the Four Rivers, Piazza Navona) was designed by Gian Lorenzo Bernini and completed in 1651 for Pope Innocent X. The four colossal river-god figures represent the four great rivers then known to geography: the Nile (Africa, head veiled because its source was then unknown), the Danube (Europe), the Ganges (Asia), and the Rio de la Plata (the Americas, shown spilling coins representing the wealth of the New World). An Egyptian obelisk (one of Rome's 13 obelisks — more than Egypt itself today, most removed as imperial trophies) rises from the center of the rock formation on which the river gods recline. The famous story: Bernini positioned the Nile figure to cover its eyes so as not to look at the Church of Sant'Agnese in Agone facing the fountain — designed by Bernini's rival Francesco Borromini. The story is apocryphal (the fountain was completed before the church façade was designed) but so compelling that it has been told for 370 years. The Piazza Navona's elongated shape directly traces the outline of Domitian's 1st-century AD stadium underneath — the race track's curve is visible in the piazza's northern end.
The Aqua Virgo was built by Marcus Agrippa in 19 BC to supply the Baths of Agrippa (the first public baths in Rome, now under the Largo di Torre Argentina area) and the general population of the Campus Martius. The name: Roman legend held that a young girl (virgo) showed the spring source to soldiers; the more prosaic reality is that the spring water had an exceptionally pure, cold character unusual in the Lazio area. The aqueduct's specific survival: unlike Rome's other aqueducts (11 were built total), the Aqua Virgo remained operational through the medieval period because its underground channel (most of the aqueduct runs underground, unlike the elevated arched aqueducts that were cut at the source by the Ostrogoth Vitigis in 537 AD) was not accessible to sabotage. The Renaissance popes who were restoring Rome (Sixtus IV, then Nicholas V) specifically restored the Aqua Virgo in 1453 and 1570 because it was the only aqueduct with a surviving channel — they renamed it Acqua Vergine. Today the Acqua Vergine supplies the Trevi Fountain, the Piazza Navona fountains, the Piazza di Spagna fountain, and approximately 2,500 Nasoni street drinking taps across the historic center.
The Nasoni (literally: big noses) are Rome's cast-iron street drinking fountains — cylindrical columns approximately 1.2 metres tall with a curved spout ("naso" — nose) that provides a continuous flow of drinking water. Rome has approximately 2,500 Nasoni in the historic center and surrounding neighborhoods, installed by ACEA (Rome's water company) from the 1870s onward on the network of the restored Acqua Vergine aqueduct. They run continuously, 24 hours a day, providing free drinking water to residents, tourists, and the city's cats and dogs. The water quality: the Acqua Vergine source (a spring near Salone, approximately 20km east of Rome) consistently produces water with very low mineral content and no chlorine taste — notably better-tasting than most bottled mineral water in Rome. How to drink from them: the spout flows continuously; cover the drain hole at the bottom of the spout with your finger to create an upward jet, or use your bottle. The Nasoni at the corner of Via della Croce and Via Condotti (near the Spanish Steps) is the most central; the one at the Largo di Torre Argentina is visible from the Republican temple excavations. Carrying a refillable bottle and using Nasoni eliminates €3-5/day in bottled water purchases.
The ten archaeological sites that every serious Italy traveler should know: (1) Ostia Antica (Rome's ancient port — more complete in some respects than Pompeii, virtually no international visitors, accessible from Rome in 35 min); (2) Paestum (Greek temples south of Salerno, 550-450 BC, better preserved than the Athenian Acropolis — three temples in a meadow with virtually no crowds); (3) Valley of the Temples, Agrigento (Sicily — seven Greek temples on a ridge above the Mediterranean, the most complete ancient Greek temple complex outside Greece); (4) Herculaneum (Campania — smaller than Pompeii, better preserved organic material, extraordinary domestic interiors); (5) Villa Romana del Casale (Sicily, Piazza Armerina — the largest floor mosaic program in the world, 3,500 square metres of 4th-century AD mosaic floors in a single villa); (6) Selinunte (Sicily — the largest Doric temple complex in the Mediterranean, five temples partially standing plus foundations of dozens more); (7) Aquileia (Friuli — the finest early Christian mosaic floor in Italy, 4th century AD, in the Basilica of Aquileia); (8) Sperlonga (Lazio coast — a coastal cave with 1st-century AD Imperial sculpture groups including the largest ancient sculptural program after the Laocoön); (9) Cuma (Campania — the oldest Greek colony in the western Mediterranean, founded 740 BC, the home of the original Sibyl of Cumae); (10) Volterra (Tuscany — the best-preserved Etruscan city, the Porta dell'Arco still standing, the Etruscan museum with the finest collection of Etruscan artefacts north of Rome).
The optimal transport strategy for a 2-week Italy trip: (1) Book Frecciarossa segments individually and early (4-6 weeks ahead, trenitalia.com or italotreno.it) — the Super Economy fares (€19-29 per segment) are significantly cheaper than any rail pass option and seat assignments are included. (2) Use regional trains for shorter distances (trenitalia.com, intercity routes, generally €5-12 per segment; no booking needed for regional trains, just validate the ticket at the platform machine before boarding). (3) Metro for Rome and Milan (Rome Metro A and B lines cover the major sites; Milan Metro M1-M5 covers all the main neighborhoods; single ticket €1.50, 24h pass €7). (4) SITA bus for the Amalfi Coast (the only public option; tickets from tabacchi shops, approximately €2.50 per leg). (5) Vaporetto for Venice (24h pass €25, 72h pass €35 — far cheaper than individual tickets if spending more than one day). (6) Circumvesuviana for Naples-Sorrento-Pompeii (€4.90 to Sorrento, €2.20 to Pompeii — the most important single regional rail line in Italy for tourists). The total transport cost for 2 weeks covering Venice-Florence-Rome-Naples circuit: approximately €150-250 per person advance booked vs €350-450 walk-up or rail pass.
Eight insights that travel books rarely include: (1) The church visiting window: almost all Italian churches are open 7-9am for morning mass before closing for the tourist rush. Arriving at 7:30am means experiencing the church in its intended liturgical context rather than as a museum — and seeing the light differently. (2) Farmacia di turno: the rotating late-night pharmacy in every Italian city is posted on every pharmacy door; Italy's pharmacists are highly trained and will advise on minor ailments without prescription. Better than urgent care for most travel health issues. (3) The afternoon closing: many family-run restaurants, shops, and small museums close from approximately 1:30-3:30pm. Planning a museum visit for 2pm often produces a closed door. (4) Train strike (sciopero) protocol: Italian trade unions are legally required to announce strikes 10 days ahead. Trenitalia publishes guaranteed minimum service tables on its website during strikes — some trains run even on strike days. Check trenitalia.com "scioperi" section if your travel dates are within a strike window. (5) The Italian Sunday: Sunday in Italy is genuinely different — most shops closed, reduced transport, but the best outdoor markets (Porta Portese in Rome, Sunday markets in regional towns) and the finest church-visiting conditions (congregations attending mass rather than tourists filling chapels). (6) Regional food ordering: every Italian region has specific dishes unavailable (or wrong) elsewhere. Ordering carbonara in Venice, or a Venetian ciccheto in Rome, produces technically competent but contextually incorrect results. Eat regional dishes in their region. (7) The tourist menu trap: "Menu turistico" means a simplified fixed-price menu using lower-cost ingredients — it is not a representative sample of the kitchen's best work. The Italian lunch pranzo menu (not tourist menu) is often excellent value. (8) Asking for the bill is not optional: in Italy, the bill does not arrive until you ask for it ("Il conto, per favore"). This is not poor service — it is the standard.
Ten photographic subjects that produce extraordinary images and appear in almost no standard Italy photography: (1) The fish market at 6am (Venice Rialto or any Sicilian port — the early market arrangement has a visual logic and color that disappears by 9am); (2) The interior of any Italian train (the Frecciarossa interior, the regional train compartment — the specific quality of Italian train light and the countryside passing are photographic subjects that few travel photographers cover seriously); (3) Food preparation visible through a kitchen or shop window (fresh pasta being made, pizza being shaped, fish being cut — the process of Italian food preparation is as photographic as the result); (4) Evening aperitivo in a non-tourist neighborhood (the Campo Santa Margherita in Venice, the Via del Pigneto in Rome, the Navigli in Milan — the aperitivo hour at 7pm produces a crowd quality and light quality unavailable at other times); (5) Architecture detail (the specific stone work, the door hardware, the street number tiles, the window iron work of Italian historic buildings are individually remarkable and collectively give a texture that wide-angle establishing shots miss); (6) The Mediterranean light at 5pm in October (the low autumnal southern light on Italian stone produces the most extraordinary photographic conditions in the Italian calendar — warmer, more raking, and less harsh than summer noon); (7) Inside a covered market (Testaccio market in Rome, Quadrilatero in Bologna, Vucciria in Palermo — the interior lighting, the vendor-produce compositions, and the buyer-vendor interactions are consistently extraordinary); (8) The transition space between tourist and local Italy — the lane where the souvenir shops end and the hardware shop begins, the corner where the piazza's tourist café gives way to the neighborhood bar.
