This morning, I had the thrill of standing beneath the Arch of Janus, and what made the experience even more special was that the gate was open, allowing me to pass through this ancient structure. There’s something exhilarating about walking beneath a monument that has stood here since the 4th century CE, witnessing the countless transitions of Rome itself. The Arch of Janus, located in the Velabrum, near the Church of San Giorgio al Velabro, is unique in Rome for its quadrifrons design—an archway with four sides supported by massive piers, creating vaulted passageways. It was likely built during the late Roman Empire, possibly under Emperor Constantine or his successors. Its name, while tied to the Roman god Janus, the deity of transitions and doorways, likely doesn’t indicate a religious function. Instead, this structure probably served a commercial or civic purpose, standing at the crossroads of the ancient Forum Boarium, Rome’s cattle market and an important trade hub. What’s striking about the arch is its use of spolia, repurposed materials from earlier structures, evident in the decorative niches that once held statues. It’s a testament to the resourcefulness of Roman architects during a time of transition and reflects the layered history embedded in every corner of the Eternal City. Standing beneath this monumental gateway, I couldn’t help but feel a profound connection to the history that unfolded here. The open gate allowed me to fully immerse myself in the moment, imagining the merchants, travelers, and citizens who once passed beneath these same arches. It was a humbling reminder of Rome’s enduring ability to bridge the past and present, offering moments of pure wonder like this one.

Il monumento sorge ai margini del Foro Boario, presso la chiesa di San Giorgio in Velabro, poco distante dal Tempio di Ercole e dal Tempio di Portuno. È uno di rari esempi di tetrastilo conservatosi fino ad oggi. Risulta edificato in gran parte con marmi e materiali di spoglio di altri monumenti precedenti, verso la metà del IV secolo, quindi con una genesi simile a quella dell'Arco di Costantino. Probabilmente deve essere identificato con l'Arcus Divi Constantini citato dai Cataloghi regionari presso il Velabro. Il nome moderno non si riferisce al dio bifronte Giano, ma piuttosto deriva dal termine latino ianus, che indica un passaggio coperto, o una porta. Come gli iani testimoniati dalle fonti nel Foro Romano, non si trattava di un arco trionfale, ma probabilmente di una struttura destinata ai banchieri che operavano nel Foro Boario. L'edificio, che ha pianta quadrata ed è alto 12 m con 16 m di lato, presenta quattro massicci pilastri che sostengono una volta a crociera. Essi sono costruiti in cementizio e rivestiti da blocchi di marmo di reimpiego. Al di sopra doveva presentare un piano attico ed un tetto forse di forma piramidale, la cui struttura in opera laterizia, che in origine doveva ugualmente essere rivestita di marmo, fu demolita nel 1827 perché a torto ritenuta parte della fortificazione medioevale impiantata sopra l'edificio romano ad opera dei Frangipane (che ne avevano anche chiuso i fornici). Nei piloni vi sono molte nicchie che forse ospitavano statue in grandezza quasi naturale, esse sono 12 su ogni faccia Est ed Ovest e 2 su ogni faccia Nord e Sud e altre 10 sono finte. In totale quindi 28. Le nicchie in origine dovevano ospitare statue ed erano inquadrate da edicole con piccole colonne, oggi perdute, poggianti sui cornicioni, ed erano coperte da una semicupola a conchiglia scolpita nei blocchi di marmo del rivestimento. Gli unici resti conservati della decorazione scultorea sono rappresentati dalle quattro figure femminili sulle chiavi di volta: si riconoscono con sicurezza la dea Roma sul lato orientale e Minerva sul lato settentrionale, mentre l'identificazione delle altre due figure come Giunone e Cerere presenta maggiori incertezze. L'Arco, oltre ad avere funzioni monumentali, serviva da riparo dall'inclemenza del tempo ai mercanti romani di bovini e ai prestatori di denaro che affollavano il Foro. Durante il medioevo, la famiglia romana dei Frangipane lo utilizzò come fortezza, chiudendone i fornici; quando queste opere furono eliminate, nel 1830, andarono perduti anche l'attico e il coronamento originari, perché non furono riconosciute come opere appartenenti alla struttura originaria.

The Arch of Janus (Arco di Giano) can be seen behind the carpark to the direct west of the Portuno Temple at Piazza della Bocca della Verita. This is a 4th-century ancient arch structure and the only surving quadrifron style arch remaining from Ancient Rome. There are niches around the outside of the Janus Arch, which would have likely held statues at some point in time. It seems there may have been added structures atop the Arch as well but these were removed in the early 19th-century under the belief at that time that they were Medieval period additions and not part of the original ancient Arch. It is convenient to have a brief look-see of the Arch of Janus before or after your visit to Santa Maria in Cosmedin church. Definitely worth a few minutes to view if you plan to see the ancient temples at Piazza della Bocca della Verita.

Ich stehe vor dem imposanten Janusbogen, einem der faszinierendsten, aber oft übersehenen Monumente Roms. Mit seinen massiven, viereckigen Steinbögen erhebt sich dieser antike Bau mitten im ehemaligen Forum Boarium, dem ältesten Marktplatz Roms, der einst ein geschäftiges Zentrum für Händler und Reisende war. Die Struktur ist beeindruckend – vier große Bögen, die in jede Himmelsrichtung führen, und eine solide Steinmasse, die dem Gewicht der Jahrhunderte trotzt. Er ist wie ein Tor durch die Zeit, das die Vergangenheit mit der Gegenwart verbindet.

Der Janusbogen, benannt nach dem doppelgesichtigen Gott Janus, soll im 4. Jahrhundert n. Chr. unter Kaiser Konstantin oder einem seiner Nachfolger errichtet worden sein. Janus, der Gott der Übergänge, der Türen und Tore, wird oft mit zwei Gesichtern dargestellt: eines, das nach vorne und eines, das nach hinten schaut. Es ist passend, dass dieses Denkmal aus vier gleich großen Durchgängen besteht, die jeweils in eine andere Richtung blicken – der ganze Bogen scheint die Idee von Übergängen und Neuanfängen zu verkörpern.

Ich gehe näher heran und spüre, wie die Zeit selbst an diesen Steinen haftet. Die Struktur ist zwar schlicht, fast ein wenig ungeschmückt, aber ihre Wucht und Schlichtheit beeindrucken mich. Im alten Rom diente der Bogen als eine Art überdachte Passage für Kaufleute, die hier vor Regen und Sonne Schutz suchten. Die Stille um mich herum lässt mich die Bedeutung dieses Ortes noch tiefer wahrnehmen – hier kamen die Römer zusammen, um Geschäfte abzuwickeln, Neuigkeiten zu tauschen und, so stelle ich mir vor, manchmal auch von den Schutzgeistern der Tore um Glück und gute Geschäfte zu bitten.

Der Bogen selbst war Teil eines umfassenderen Systems von Monumenten und Gebäuden im Forum Boarium, das damals eine lebhafte Kreuzung am Rande des Tiber war. Ich kann fast das geschäftige Treiben hören: Stimmengewirr, das Klappern von Hufen, der Duft von frischen Waren, die auf den Marktständen angeboten wurden. Heute aber ist der Janusbogen ein stiller Beobachter der Stadt, umgeben von modernen Gebäuden und dem stetigen Strom der römischen Straßen.

Die Oberfläche des Janusbogens trägt die Zeichen der Zeit, verwittert und von Pflanzen überwuchert, die in den Spalten der Steine wachsen. Die einstigen Nischen, in denen Statuen und vielleicht sogar Götterbilder standen, sind leer – ein mysteriöser Verfall, der mich an die Vergänglichkeit und den ewigen Kreislauf von Leben und Tod erinnert. Ich frage mich, wie viele Generationen von Römern hier entlanggegangen sind, ohne zu ahnen, dass ihr täglicher Weg eines Tages Geschichte sein würde.

Ich lasse meinen Blick ein letztes Mal über die vier Durchgänge gleiten, die in alle Richtungen weisen. Der Janusbogen ist mehr als ein Durchgangsort, er ist ein Monument für die Bewegung, für Übergänge, für das Kommen und Gehen – ein Symbol dafür, wie Rom seit Jahrhunderten das Alte bewahrt und das Neue begrüßt. Mit diesem Gedanken gehe ich weiter, fühle mich aber durch diesen kurzen Moment der Vergangenheit verbundener als zuvor.

There are a number of Roman antiquities in Rome that you can visit and see for free, and this is one. It's a quiet peaceful place with a beautiful structure and recently partially cleaned. There's no posted signage (as of 6/2021) but this beautiful arch has been cleaned now on the side that faces the Portunus and the Round Temple. There's a gate around it, which seems to be kept closed all the time, but the bars are spaced wide enough that you can sneak a 77mm lens through for some nice photos or simply a nice view. You can walk all around it also. There's parking at the back, though I'm not sure about restrictions. From the back, it's a nice walk up to the Capitoline Museum and a side of the forum that also affords a nice free place to take photos of the Curia and the temple of Saturn. From the cleaned side it's just across the street from Portunus. Ramage's guide speculates that it may really have been an arch of the deified Constantine, but as a fan of Janus, I prefer to...
