The Stadium of Domitian: What Lies Beneath
The Stadium of Domitian (Stadio di Domiziano) was built in approximately 86 AD by the Emperor Domitian as Rome's only purpose-built Greek-style athletic stadium, designed for foot races, long jump, and discus competitions rather than gladiatorial combat or chariot racing (which took place in the Colosseum and Circus Maximus respectively). The stadium measured approximately 276m × 106m and could seat approximately 30,000 spectators. It was used for the Greek-style athletic games (the Agon Capitolinus) that Domitian introduced to Rome, imitating the Greek Olympic tradition that Romans had never fully adopted into their own festival calendar.
The stadium's elongated oval form, a semicircular north end, straight sides, semicircular south end, is exactly preserved in the shape of Piazza Navona. The stadium's ancient walls form the foundation of the Renaissance palazzi that line the piazza today. The spectator seating vaults on the east side of the stadium are visible in the lower floors of the buildings on the piazza's eastern edge. The curved northern end of the piazza (where Piazza Navona's characteristic oval shape is most pronounced) sits directly over the north semicircle of the ancient stadium's turning end.
The underground stadium visit: Accesso al Sottosuolo dello Stadio di Domiziano (entrance at Piazza di Tor Sanguigna 3, the north end of the piazza, below street level). Tickets: €8, open daily 10:00–19:00. The excavation shows approximately 100 meters of the stadium's south-to-north corridor, the ancient brick vaulting, the stone seating structure, and marble inscriptions and architectural fragments found during excavation. The most significant element: the stadium's central spine wall (spina), still partially standing in the underground space, showing the turning-post structures used in athletic events. The visit takes 45–60 minutes and fundamentally transforms the visitor's understanding of what the piazza above is built on.
From Stadium to Piazza: 1,400 Years
After the end of the Western Roman Empire in 476 AD, the stadium continued in use as a market and performance space, the word "navona" is almost certainly derived from "agone" (the Greek word for athletic competition, which gave the stadium its full name: In Agone), transformed by medieval Roman dialect into "navone" and then "navona." The curved form of the stadium's arena floor became the piazza's floor plan naturally, as the population settled into the stadium's arcades and corridors for shelter and commerce.
The medieval Piazza Navona was Rome's most important fruit and vegetable market, the elongated enclosed space was right for stalls, and the surrounding arcaded structure (the ancient stadium vaults converted to shops and houses) provided covered storage. This market function continued from the medieval period until 1869, when the market was moved to Campo de' Fiori and the piazza was redesigned as an ornamental public space.
The transformation into the Baroque piazza we see today occurred primarily in the 17th century, during the reign of Pope Innocent X (Giambattista Pamphilj, pope 1644–1655), whose family palace (Palazzo Pamphilj, now the Brazilian Embassy) occupies the piazza's western side. Innocent X's investment in the piazza, commissioning Bernini's Fountain of the Four Rivers, funding the rebuilding of Sant'Agnese in Agone by Borromini, and orchestrating the piazza as a setting for Pamphilj family displays of power, transformed it from a market to a monument.
The Three Fountains
Piazza Navona has three fountains arranged along its long axis:
Fontana del Moro (south end): The southern fountain was designed by Giacomo della Porta in 1574 and features a triton wrestling with a dolphin in the center of a basin. The central figure of a Moor (a dark-skinned figure wrestling the dolphin, giving the fountain its name) was added by Bernini in 1653 as part of the piazza's overall Baroque redesign, a replacement for the 16th-century triton figure in the center. The Moor figure is a later copy. The original Bernini marble is in the Galleria Borghese.
Fontana del Nettuno (north end): The northern fountain was also designed by della Porta in 1574 as a simple basin without a central figure. The Neptune group in the center. Neptune wrestling an octopus, surrounded by sea horses, nereids, and sea creatures, was added in 1878 by Antonio Della Bitta and Gregorio Zappala, giving the fountain its current elaborate form. The 1878 addition is later than the surrounding architecture and doesn't perfectly integrate with the overall Baroque program of the piazza.
Fontana dei Quattro Fiumi (center): The masterwork of the piazza, described in the next section.
The Four Rivers Fountain: Bernini's Program Decoded
The Fontana dei Quattro Fiumi (Fountain of the Four Rivers, 1648–1651, Gian Lorenzo Bernini) is the definitive statement of Baroque fountain design and the most theatrically ambitious public sculpture in Rome. The program: an artificial rock formation (travertine and pumice, designed to appear natural) rising from a large oval basin, supporting an Egyptian obelisk (the Obelisk of Domitian, originally from the Circus of Maxentius on the Appian Way, transported to the piazza) flanked by four colossal marble figures representing the four great rivers then known to European geography.
The four river figures:
- The Nile (Africa): The only figure with a draped head, the source of the Nile was unknown to Europeans in 1651, and the covered face represents geographical ignorance of the river's origin. The cloth isn't modesty. It is cartographic uncertainty made marble.
- The Ganges (Asia): Holding an oar, representing navigability, the Ganges was understood by 17th-century Europeans primarily as a trade route.
- The Danube (Europe): Reaching toward the papal coat of arms on the obelisk base, the figure closest to the Pamphilj family palace, acknowledging the patron.
- The Rio de la Plata (Americas): Raised arm, coins scattered at the figure's feet, representing the wealth flowing from the Americas to Europe. The raised arm is traditionally interpreted as shielding from the facade of Borromini's Sant'Agnese church opposite, as if frightened the facade will collapse, a theatrical joke that Bernini supposedly inserted to mock his rival. The story is probably false (the fountain was completed before the facade was designed), but the visual tension between the raised arm and the church across the piazza is genuine.
The obelisk: The Egyptian obelisk supported by the rock formation is original Egyptian granite (from the reign of Domitian, 81–96 AD, a Roman-period obelisk made in Egypt rather than an ancient Egyptian original), moved from the Circus of Maxentius. The top is crowned by the Pamphilj dove carrying an olive branch, the family symbol of Innocent X, placed to mark the piazza as Pamphilj territory.
Bernini vs. Borromini: Architecture's Greatest Rivalry
Gian Lorenzo Bernini (1598–1680) and Francesco Borromini (1599–1667) were born one year apart, worked in Rome simultaneously for 40 years, competed for the same commissions, and produced the two most important bodies of work in Baroque architecture and sculpture. Their rivalry was personal, professional, and, in contemporary sources, genuinely hostile.
Bernini was the establishment figure: papal favorite (he worked for eight consecutive popes from Paul V to Innocent XI), socially adept, prolific, wealthy, and the designer of the most grandiose Baroque programs in Rome (the colonnade of St. Peter's Square, the baldacchino inside St. Peter's, the Four Rivers Fountain). Borromini was the technical genius who worked for Bernini as a draftsman before striking out independently, produced more formally innovative architecture (Sant'Carlo alle Quattro Fontane, Sant'Agnese in Agone, the Oratorio dei Filippini), and was temperamentally isolated, uncompromising, and ultimately suicidal, he stabbed himself with a sword in 1667, dying from the wound.
The specific Piazza Navona episode: Pope Innocent X initially commissioned Borromini for the Four Rivers Fountain before switching to Bernini after Bernini presented a model of the fountain to the pope through intermediaries (the pope had stated he wouldn't commission Bernini, but after seeing the silver model, which Bernini had placed where Innocent X was certain to see it, changed his mind). The professional slight to Borromini was acute. The next competition between Bernini's fountain and Borromini's church facing each other across the piazza, two masterworks by rival geniuses, forced into perpetual dialogue, is one of the finest dramatic situations in architectural history.
Sant'Agnese in Agone
Sant'Agnese in Agone (the church on the western side of the piazza, 1652–1655, primarily by Francesco Borromini with earlier work by Girolamo Rainaldi) is the finest example of Borromini's mature church design in Rome. The facade, a convex-concave-convex composition that curves inward and outward in the horizontal plane, creating a dynamic tension absent from flat Baroque facades, was one of the most formally radical solutions in 17th-century architecture. The twin bell towers flanking the central dome are the only surviving example of Borromini's tower design in Rome.
Interior: the church contains the relics of Sant'Agnese (a 13-year-old Roman girl martyred in 304 AD on this site, where the stadium's prostitution trade was conducted, the specific location of her martyrdom giving the church its name). The reliquary chapel contains her skull. The church is open to visitors (free, 09:30–12:30 and 15:30–19:00, closed Monday) and is one of the most undervisited significant churches in Rome, the position on Piazza Navona means most visitors look at it from outside rather than entering.
The Flooded Piazza Tradition
Every August Saturday and Sunday in the 18th and 19th centuries, the drainage plugs at the bases of all three fountains in Piazza Navona were opened, and the water flowed out of the fountains and across the piazza until the entire oval space was ankle-deep in water, a lake in the middle of Rome. The Pamphilj family (who controlled the piazza through their palazzo) arranged this specifically as a spectacle: the wealthy arrived in carriages (which could be driven through the shallow water), creating their own moving island amid a wading crowd. The tradition was abandoned in 1867, reportedly when the water became too contaminated for the spectacle to be elegant. The memory of it explains why the piazza's level is very slightly lower at the center than at the edges, a drainage gradient still visible in the cobblestones.
Q&A: Piazza Navona Questions
Is Piazza Navona free to visit?
The piazza itself is free, open 24 hours, with no entry requirement. The fountains can be photographed from any angle without restriction. The underground stadium visit (Sottosuolo dello Stadio di Domiziano) costs €8. The church of Sant'Agnese in Agone is free. The restaurants and cafés in and around the piazza have the standard tourist-area pricing, check menus before sitting down.
When is Piazza Navona least crowded?
06:00–08:00 on any day. The piazza is used by local dog walkers and delivery workers at this hour. The fountains are lit all night and still illuminated at dawn. By 09:30, the first day-tripper groups arrive. By 11:00 in peak summer, the piazza is densely crowded. The Christmas market (mid-December through January 6) fills the piazza with temporary stalls. It is festive and crowded simultaneously.
What is the history of the Pamphilj family's connection to Piazza Navona?
The Pamphilj family (whose most famous member was Pope Innocent X, born Giambattista Pamphilj, 1574–1655) owned the palazzo on the western side of the piazza and effectively controlled the piazza as a family domain during the 17th century. Innocent X's investment in the piazza, the Four Rivers Fountain, the rebuilding of Sant'Agnese, the paving and regularization of the oval space, was simultaneously an act of civic patronage and family aggrandizement. The piazza as we see it today is substantially the vision of one family and one pope. After Innocent X's death, the family's influence declined but the piazza remained. The palazzo is now the Brazilian Embassy.
What Nobody Tells You About Piazza Navona
The Fountain Figures Aren't All Bernini's Hand
Bernini designed the Four Rivers Fountain in its entirety and produced the concept models and the overall program. But the four river figures were executed by a workshop team rather than by Bernini personally, the Nile was carved by Giacomo Antonio Fancelli, the Ganges by Claude Poussin (a French sculptor working in Rome, brother of the painter Nicolas Poussin), the Danube by Antonio Raggi, and the Rio de la Plata by Francesco Baratta. Bernini's personal contributions to the actual marble carving are limited to certain details of the rock formation and the dove at the top. This was standard practice for major commissions in the period, the master designed and directed. The workshop executed. But the tour-guide narrative of "Bernini carved this" isn't precisely accurate.
There Is an Egyptian Obelisk in the Piazza's Underground
The obelisk currently supporting the Four Rivers Fountain isn't the original obelisk on the site, the original was toppled and broken in the medieval period. The current obelisk (from the Circus of Maxentius on the Appian Way, transported in 1648) was selected because it was the most intact available obelisk in the Rome area at the time. In the underground stadium space beneath the piazza, fragments of the original Domitian-era obelisk are visible, the hieroglyphic-carved fragments that weren't reused in the replacement. These fragments are visible in the underground visit and document the site's complete obelisk history from the 1st to the 17th centuries.

Piazza Navona Year-Round: The Seasonal Character
Piazza Navona's character changes seasonally in ways that affect the visitor experience significantly:
Summer (June–August): The piazza is at maximum tourist density from 10:00 to 22:00. The open café tables in front of Tre Scalini (the historic café on the west side of the piazza, famous for the tartufo, the chocolate truffle ice cream it invented in 1946) are occupied for hours by tourists eating extremely expensive gelato (€8–12 for the tartufo at table price) while street painters and tourist-facing performers circulate continuously. The genuine Piazza Navona experience in summer requires being there at dawn (06:00–07:30) or late evening (22:30 onwards).
Winter (December–January 6): The Fiera di Befana, the traditional Roman Christmas and Epiphany market that has occupied Piazza Navona since at least the 17th century, fills the piazza with stalls selling toys, sweets (particularly the Befana candy, coal-shaped black sugar candy, a reference to the Italian tradition that the witch Befana delivers coal to naughty children and sweets to good ones on January 5), and Christmas decorations. The market runs from early December to January 6 (Epiphany), when Italian Christmas tradition ends. It is genuinely Roman (not the German-influenced Christmas market style that has spread to most Italian cities) and genuinely atmospheric. It is also crowded and loud. The combination of the Baroque architecture, the lit fountains, and the traditional Italian market character produces the finest winter piazza experience in Rome.
The piazza at dawn in any season: Piazza Navona at 06:30 on any morning is the most peaceful major public space in Rome, the fountains running, the pigeons settling, the early-rising residents crossing through on their way to work, the architecture visible without the crowd density that fills it 2 hours later. The dawn arrival also catches the specific morning light on the Borromini facade (east-facing, catching the early eastern light directly) that the afternoon and evening visits don't provide.
Q&A: Piazza Navona History and Visiting
How long should I spend at Piazza Navona?
The piazza itself, the fountains, the church exterior, the general atmosphere, requires 30–45 minutes as a surface visit. Adding the underground stadium visit (45–60 minutes): total 1.5 hours. Adding a sit-down coffee at a café table (30–45 minutes): 2 hours. The piazza isn't a museum. There is no minimum time requirement and no need to see "everything." Walk around all three fountains, examine the Four Rivers figures at close range, look at the church facade for Borromini's convex-concave composition, and decide whether the underground visit interests you. The quality of the experience is more about engagement than duration.
What is the relationship between Piazza Navona and Caravaggio?
Direct: Caravaggio spent significant time in the area around Piazza Navona in the 1590s–1600s (his studio was near the Palazzo Madama, adjacent to the piazza's northern end) and the street fight in which he killed Ranuccio Tomassoni on May 28, 1606, the event that forced him to flee Rome, took place on Campo Marzio near Piazza Navona area (the exact location is disputed in historical sources). Two of Caravaggio's most important paintings are in the nearby church of San Luigi dei Francesi (3 minutes walk east of the piazza), the Calling of Saint Matthew and the Martyrdom of Saint Matthew. Piazza Navona neighborhood is thus the center of gravity of Caravaggio's Rome career.
Is the Sant'Agnese in Agone church worth entering?
Yes, the Borromini interior is the finest example of his mature church design and is free to enter. The specific features to observe: the convex drum beneath the dome (Borromini's unconventional solution that gives the dome its characteristic externally visible profile). The Baroque illusionism of the pendentives and squinches supporting the dome (creating a transition from square base to circular dome that Borromini solved with extraordinary technical invention). And the reliquary chapel of Sant'Agnese in the first chapel left of the altar. Open daily except Monday, 09:30–12:30 and 15:30–19:00. Average visitor time: 15–20 minutes.
