The Trevi Fountain is Rome's most visited monument. Almost nobody knows why it was built where it was, who designed it, or where the coins go. Here is the complete history.
Plan my Italy trip →The Trevi Fountain is the most visited monument in Rome after the Colosseum. Almost nobody knows why it was built where it was, who actually designed it, how long it took, or where the €1.5 million in coins thrown annually actually goes. Here is the complete history — the ancient aqueduct that makes the whole thing work, the 18th-century papal competition, and the specific stories the tourist crowds don't know.
The Trevi Fountain is at the end of the Acqua Vergine — one of ancient Rome's eleven aqueducts, built by Marcus Vipsanius Agrippa in 19 BC to supply the Baths of Agrippa and the surrounding Campus Martius district. The aqueduct carries water from springs 20km east of Rome (the Salone springs, still the source today) through a system that has operated continuously for 2,045 years. The Acqua Vergine is the only ancient Roman aqueduct still supplying water to Rome without a pump — it runs entirely by gravity from the spring source to the city at a gradient of approximately 25cm per km. The name Vergine (Virgin): the ancient tradition holds that a young girl (vergine) showed the location of the springs to Agrippa's soldiers; the story is likely legendary but the name persisted through 2,000 years of continuous use. The specific location of the fountain: the "trevi" refers to the tre vie (three roads) that converged at this point in the ancient city — a major intersection where the aqueduct water arrived in the neighborhood. Every large fountain in historic Rome marks an aqueduct terminal; the Trevi marks the end of the most important one. The hydraulic engineering that powers the fountain requires no pumps — the water pressure is entirely gravitational, as it was in 19 BC.
The popular story that Bernini designed the Trevi Fountain is incorrect. Gian Lorenzo Bernini (1598-1680) designed a preliminary version commissioned by Pope Urban VIII in the 1640s, but the project was abandoned after Urban VIII's death in 1644 and the Barberini family's fall from papal favor. The fountain that exists was commissioned by Pope Clement XII in 1730 — 50 years after Bernini's death — through an open competition. Alessandro Galilei (the architect who designed the facade of the Lateran Basilica) initially won, but the competition was controversial (Galilei was Florentine; Roman architects protested) and Clement XII subsequently awarded the commission to the Roman architect Nicola Salvi (1697-1751). Salvi began construction in 1732 and worked on the project until his death in 1751, when it was approximately 80% complete. The fountain was finished and inaugurated by Pope Clement XIII in 1762 — 30 years after construction began, 12 years after Salvi's death. The theatrical back wall composition (the Palazzo Poli was specifically purchased by the papacy to serve as the fountain's background) and the specific integration of architecture, sculpture, and water that makes the Trevi uniquely successful was Salvi's design concept. The coin tradition: the practice of throwing a coin over the left shoulder to guarantee a return to Rome is documented from the 19th century (post-fountain construction); the specific "three coins" ritual (one to return, two for love, three for marriage) was popularized by the 1954 film Three Coins in the Fountain.
Ten Italian cities that rarely appear on first-trip itineraries but deliver experiences comparable to the main triangle: (1) Lecce (Puglia — the Baroque capital of southern Italy, with a specific local sandstone (pietra leccese) that carves to extraordinary detail; the Basilica di Santa Croce facade is the most ornate Baroque building in Italy; the old city is compact and walkable, the nightlife around Piazza Santo Oronzo is excellent, and the accommodation is significantly cheaper than Florence or Rome); (2) Matera (Basilicata — one of the oldest continuously inhabited cities in the world, the cave-dwelling sassi have been occupied for 9,000 years; UNESCO World Heritage and European Capital of Culture 2019; approaching by car at dusk from the Murgia plateau opposite gives the most extraordinary Italian urban view after the Amalfi Coast); (3) Verona (Veneto — the Roman Arena (still used for opera, the largest surviving Roman amphitheater after the Colosseum), the Romeo and Juliet tradition, the superb Piazza delle Erbe market, 1h from Venice and 1.5h from Milan; consistently overlooked); (4) Lucca (Tuscany — the only Italian city with intact Renaissance walls (converted to a public promenade and bike path), the Torre Guinigi with the trees growing from the top, the extraordinary density of Romanesque churches in a compact pedestrian center, and almost no visitors compared to Pisa or Florence 30 minutes away); (5) Trieste (Friuli-Venezia Giulia — the Habsburg port city, the most Central European Italian city, the extraordinary coffee bar culture (the local espresso terminology is completely different from the rest of Italy), James Joyce lived and wrote here 1904-1915, and the Carso plateau above the city gives the most unusual Italian landscape in the north); (6) Orvieto (Umbria — the most spectacular Italian hilltop city after Matera, with the cathedral facade (begun 1290) producing the finest Gothic facade in Italy; the underground Etruscan and medieval cave network below the city; 1h15 by train from Rome and an obvious overnight from the capital); (7) Bari Vecchia (Puglia — the medieval old city of Bari, with the Basilica di San Nicola (the finest Norman church in Puglia), the fishermen's wives making orecchiette by hand in the streets outside their front doors (Via dell'Arco Basso and the surrounding lanes), and the most authentic street food in southern Italy at a fraction of the Naples prices); (8) Ravenna (Emilia-Romagna — eight UNESCO World Heritage monuments in a small city; the 5th-6th century mosaics at the Mausoleum of Galla Placidia, San Vitale, and Sant'Apollinare Nuovo are the finest Byzantine art in the Western world, rivaling the Hagia Sophia; 1h30 from Bologna by train); (9) Alberobello (Puglia — the trulli district, a UNESCO World Heritage town of conical stone-roofed houses unique in the world, entirely concentrated in the Rione Monti area; worth a half-day from Bari or a night in a trullo house); (10) Ferrara (Emilia-Romagna — the Renaissance Este court city, a UNESCO World Heritage site, with the Castello Estense moated castle, the most complete Renaissance urban plan in Italy, and the best bicycle culture of any Italian city).
Eight things experienced Italy visitors consistently say they wish they had known on their first trip: (1) The advance booking requirement is real and not optional. The Vatican Museums, the Colosseum, the Borghese Gallery, the Uffizi in summer — these are not "nice to pre-book" suggestions. Arriving without a booking in July produces either a 2-3 hour queue or no entry. The booking fees (€4-5 per ticket) are the best money spent in Italy. (2) The best food is never near the tourist monuments. The 300-metre rule applies in every Italian city: walk 300 metres from any major monument and the restaurant quality improves by approximately 30-40% and the price drops by 20-25%. (3) Italian cities are best experienced at city pace, not monument pace. Two hours at the Uffizi produces better memories than three museums in a day — the specific Florentine quality comes from the Botticelli room, not from having been to the Bargello and the Accademia on the same day. (4) September and October are better than July and August for almost everything. Slightly lower temperatures, significantly lower crowd density (20-40% fewer visitors at major sites after Italian school return), lower accommodation prices, and the specific quality of Italian autumn light. The only trade-off: the Cinque Terre trails and some mountain huts begin closing in mid-October. (5) The Italian lunch hour is still real. Many churches, smaller museums, and shops close 1-3pm or 12:30-3:30pm. Planning around these hours (museums before noon, long lunch during the siesta, afternoon activity from 4pm) is not time wasted. (6) The train is always better than the car in cities. Parking in Rome costs €20-30/day in a garage (street parking is essentially unavailable); in Florence the ZTL restricted zone covers the entire historic center with €100 fines for unauthorized entry; in Venice there are no cars. The Frecciarossa is faster than driving between major cities and drops you in the city center. (7) Italian coffee culture is specific and worth learning. The 30 seconds standing at an Italian bar counter, ordering espresso by making eye contact, paying €1.50, and drinking it immediately is one of the most compressed expressions of Italian daily culture. Ordering a "large coffee" or a Starbucks-style drink at an Italian bar misses the point and the experience. (8) Free doesn't mean lesser in Italy. The Pantheon interior (€5, originally free), the Trevi Fountain, the Spanish Steps, the 900 churches with extraordinary art — the cost of experiencing the finest things in Italy is very low if you know which things are free. The €20 Vatican Museums and the €0 church with a Caravaggio down the street are 200 metres apart.
Ten granular Italy practical tips from experience: (1) The Vatican dress code turns people away without sympathy. The guards at St. Peter's Basilica will turn away anyone with bare knees or bare shoulders, regardless of how much they paid for their flight or how far they traveled. The solution is always to carry a pashmina or light jacket that can be wrapped around the waist for knees and draped over the shoulders. €5 shawls are sold outside; buying one in advance is better. (2) The Colosseum is always worth seeing from outside, even without a ticket. The Forum is the real prize — the valley between the Palatine and Capitoline Hills containing 1,000 years of Roman civic architecture — and it is included in the Colosseum ticket. (3) Book train tickets on the specific departure you want, not a flexible ticket. The Frecciarossa "Base" fare is €19-29; the "Flex" fare is €49-69. The difference is the ability to change. For planned trips, Base is always the right choice. (4) Pharmacists in Italy are more medically capable than in most countries. For minor ailments, the farmacia (look for the green cross) can advise and dispense treatments without a doctor visit. This saves the cost and delay of finding an English-speaking medical service. (5) The "no photos" rule in the Sistine Chapel is enforced by guards with whistles. The flash photography ban is absolute (flash damages the Michelangelo ceiling's colors). Phone photography without flash is technically banned but practically monitored inconsistently at crowd times. The guards will loudly stop anyone who tries to take photos. (6) Via del Corso in Rome and Via Tornabuoni in Florence are the main shopping streets and are designed for window shopping, not bargain purchases. The independent shops on the parallel streets sell the same brands at lower tourist markup. (7) The Italian "€1 entry fee" is often not optional. Some churches charge €1-3 to enter even though the church appears free; the fee is collected at a small desk inside. This is legitimate and goes to church maintenance. (8) The orange grove and citrus garden rule. Any restaurant near a lemon grove on the Amalfi Coast or an orange grove in Sicily that prominently features the citrus in its decor will charge a significant premium for that view. The food will be adequate. Walk away from the grove view by 50 metres and the price drops 25%. (9) Vaporetto day passes in Venice are genuinely worth buying. The €25 24-hour pass covers unlimited journeys on the main vaporetto lines; at €9.50 per single journey, 3 journeys makes it worthwhile. Book online at actv.it to avoid the queue at Santa Lucia. (10) The single most reliable restaurant quality indicator in Italy is the presence of local workers at lunch. Any trattoria, osteria, or tavola calda where Italian-speaking workers are eating their midday meal at 12:30-1:30pm on a weekday will serve real, affordable food. Follow the workers.
