TheBaths of Caracalla (Italian:Terme di Caracalla) inRome,Italy, were the city's second largestRoman public baths, orthermae, after theBaths of Diocletian. The baths were likely built between AD 212 (or 211) and 216/217, during the reigns of emperorsSeptimius Severus andCaracalla.[2] They were in operation until the 530s and then fell into disuse and ruin.
Both during and since their operation as baths, they served as inspiration for many other notable buildings, ancient and modern, such as theBaths of Diocletian, theBasilica of Maxentius, the originalPennsylvania Station in New York City,Chicago Union Station and theSenate of Canada Building. Artworks recovered from the ruins include famous sculptures such as theFarnese Bull and theFarnese Hercules.
Today the Baths of Caracalla are atourist attraction.
Construction of the baths was probably initiated by emperorSeptimius Severus and completed during the reign of his son,Caracalla. They were inaugurated in AD 216. The baths were located in the southern area of the city,Regio XII Piscina Publica, where members of the Severan family commissioned other construction works: theVia Nova leading to the baths and theSeptizodium on nearbyPalatine Hill.[3]: 7 The site chosen for the baths formerly belonged to a vast garden estate known as thehorti Asiniani, developed byGaius Asinius Pollio during the reign ofAugustus.[4] TheFarnese Bull sculptural group that was later moved into the Baths of Caracalla was already present at the site in the time of Pollio, who had imported it to display in his gardens.[4]
The estate of Pollio was appropriated by Caracalla to build his baths; the existing structures were demolished in some cases to their ground floors, filled in with earth and incorporated into the foundations of the new complex. The remains of one of these structures, a nobledomus (house), were excavated initially byFrancesco Ficoroni in the mid-18th century and again in 1860–67 by G.B. Guidi.[5] Recently this two-storey domus deep below the baths, built in 134-138 during the reign ofHadrian,[6] and partially demolished in 206 has been opened to the public revealing lavishly decorated frescoed ceilings and alararium, a room dedicated to Roman and Egyptian gods.[7]
For work to have been mostly completed in the time of Caracalla, workers would have to have installed over 2,000tonnes (2,200short tons) of material every day for six years.[8]
Work on additional decorations continued under Caracalla's successorsElagabalus andSeverus Alexander. The baths were likely mostly finished by 235. Later renovations were conducted underAurelian (after a fire) and byDiocletian. UnderConstantine the Great thecaldarium was modified.[3]: 7–8
The building was heated by ahypocaust, a system of burning coal and wood underneath the ground to heat water provided by a dedicatedaqueduct. The baths were free and open to the public.
The baths were fully functional in the 5th century when they were referred to as one of the seven wonders of Rome.Olympiodorus of Thebes mentions a capacity of 1,600. This is interpreted to refer to the maximum number of simultaneous visitors, as the daily capacity is thought to have been 6,000 to 8,000 bathers.[3]: 8
The baths remained in use until the 6th century. In the mid-4th century a Christian pilgrimage site came into being, known as thetitulus Fasciolae, close to the baths near the Church ofSanti Nereo e Achilleo. The baths thus became useful to pilgrims and the Church community for their water supply.[4] In 537 during theGothic War,King Vitiges of theOstrogoths laid siege to Rome and severed the city's water supply. Shortly thereafter the baths were abandoned.[9] Located too far away from the still-populated area of Rome, the baths were mostly disused but in the 6th and 7th centuries were apparently used for the burials of pilgrims who died after being cared for in the nearbyxenodochium of Santi Nereo e Achilleo. Some simple tombs from this era have been found inside the bath area.[3]: 8–9
PopesAdrian I,Sergius II andNicholas I may have had some work done on the aqueduct through the 9th century.[3]: 9
The earthquake of 847 destroyed much of the building, along with many other Roman structures.[10]
At least since the 12th century the baths were used as a quarry for construction materials, and of decorative pieces to be reused in churches and palaces (e.g. inPisa Cathedral andSanta Maria in Trastevere).[3]: 9
During the 14th century, the area was used as vineyards and gardens. In the 15th century, PopePius II used stone from the Baths in the construction of the Loggia of the Benediction atSt. Peter's Basilica.[11] In 1524, PopeClement VII granted an excavation license to CardinalLorenzo Pucci to remove unlimited quantities of columns, marble, travertine and other ancient stone from the Baths of Caracalla for a new palace the Cardinal was building near St. Peter's.[12] In the mid-16th century Clement's successorPope Paul III had excavations conducted in the area during the construction of his new villa. Substantial architectural decoration remained standing at this time, as documented in the drawings of the Renaissance architectsAndrea Palladio,Giovanni Antonio Dosio andAntonio da Sangallo the Elder.[13]
The excavations of Paul III between 1545 and 1547 uncovered many large statues made of marble and bronze, as well as innumerable architectural fragments, lamps, intaglios, and cameos. The quantity of materials was so great that a museum was created to house the collection, known as the Museo Farnese (relocated to the Real Museo Borbonico in the late 18th century).[14] The pope granted the area to the Roman Seminary of theJesuits. It was used as a playground for children.Philip Neri may have brought children from his oratory here—he is believed to have commissioned the frescoMadonna supported by an angel still located in thenatatio.[3]: 10–2
Between the 16th and 18th centuries interest in the structure was rekindled and several famous architects made drawings of the ruins (Andrea Palladio,Giovanni Battista Falda,Giambattista Nolli andGiuliano da Sangallo).[3]: 12
The aqueduct serving the baths was in use up to the 19th century. The Aqua Antoniniana aqueduct, a branch of the earlierAqua Marcia also worked on under Diocletian, was specifically built to serve the baths.[citation needed]

In 1824, excavations at the baths were conducted by Count Egidio di Velo, whose findings included the mosaics showing athletes now at theVatican Museums. Further work followed byLuigi Canina in thefrigidarium (until the mid-19th century) and then by Battista Guidi (1860–7).[3]: 12
From 1866 to 1869 restoration work in the central part of the complex revealed a torso of Hercules, porphyry columns and figure-adorned capitals. In 1870, the area became the property of the Italian government andPietro Rosa conducted excavations in the easternpalaestra. In 1878–9,Giuseppe Fiorelli discovered mosaics in thecaldarium and westernpalaestra.[3]: 14
From the early 20th century, excavations expanded into the outer areas of the complex and downward, revealing the subterranean passages, including aMithraeum (see below). Systematic work on the galleries, started in the 18th and 19th centuries, resumed after 1901. On the eastern side more work was done in the late 1930s, when an opera stage was installed in thecaldarium. Except for some sketches no documentation of these restorations survives.[3]: 14
Further restoration work took place in the 1980s, when thick vegetation and illegally built houses in the area were cleared away. The southern wall with its cisterns, the southwestern library and the octagonal hall known as the Temple of Jupiter were restored at that point. In 1998–9, the opera stage was dismantled and modern visitor facilities were added to the baths. They reopened to the public in 2001.[3]: 14
The baths were the only archaeological site in Rome to be damaged byan earthquake near L'Aquila in 2009.[15] They experienced minor damage in August 2016 from anearthquake in central Italy.[16]
The bath complex covered approximately 25 hectares (62 acres). The complex is rectangular, measuring 337 m × 328 m. Its construction involved the moving of a substantial amount of earth, as parts of the nearby hills had to be removed or leveled into platforms. Several million bricks were used in the construction. The baths contained at least 252 columns, 16 of which had a height of over 12 m.[3]: 19
Water was carried to the baths by the then newly constructed Acqua Antoniniana, from the major Acqua Marcia. The exact path of the aqueduct supplying the baths is not known as only a few segments have been discovered. The aqueduct connected to the southern side of the baths where it filled 18 cisterns. These in turn were connected by lead pipes with the baths proper.[3]: 20–1
The baths followed the "great Imperial baths" blueprint for Roman baths. They were more a leisure centre than just a series of baths. Besides being used for bathing, the complex also offered facilities for taking walks, reading/studying, exercise and body care. The main building stood in the centre with no connections to the surrounding walls, which housed the cisterns, two symmetrical libraries (south), two largeexedras (east and west) andtabernae (shops) to the north. The surviving library measures 38 m × 22 m. Between the outer wall and the central complex were gardens (xystus).[3]: 25–7
The axis of the baths was laid out in a northeast to southwest fashion to make use of the sun's heat. Thecaldarium faced southwest, thefrigidarium northeast. Overall, the bath area was arranged along a single linear axis. However, dressing rooms andpalaestra were arranged symmetrically on both sides of the building, giving easier access and facilitating the flow of people in and out of the thermal area, thus increasing the number of potential users of the baths.[3]: 22
The bath main building was 214 m × 110 m and the height to the top of the roof line was 44 m (145 ft); it covered 2.6 hectares (6+1⁄2 acres) and could hold an estimated 1,600 bathers.[17]
The baths were the second to have a publiclibrary within the complex. Like other public libraries in Rome, there were two separate and equal sized rooms or buildings; one forGreek language texts and one forLatin language texts.[18] The surviving library had three walls covered by niches (a total of 32) that housed the books. A larger niche in the middle of the southern wall likely contained a statue. A masonry ledge in front of the three other walls probably served as a bench. The floor is made from marble.[3]: 26–7
The baths consisted of a centralfrigidarium (cold room) measuring 58 m × 24 m (190 ft × 79 ft) under threegroin vaults 32.9 m (108 ft) high, a double pooltepidarium (medium), and a circularcaldarium (hot room) 35 m (115 ft) in diameter, as well as twopalaestras (gyms where wrestling and boxing were practiced). The northeastern end of the bath building contained anatatio or swimming pool.[17] Thecaldarium had seven pools, thefrigidarium four, thetepidarium two. Next to thecaldarium were saunas (laconica).[3]: 28
The central room was thefrigidarium, whose high roof was supported by eight giant columns made from Egyptian granite. Walls and floor were made from marble. The hall served a dual purpose: It was a meeting place and transition area for visitors heading for other parts of the bath. It also housed the cold baths, in the form of four pools, two of which were connected to thetepidarium and two of which communicated with thenatatio via some waterfalls. In the middle of thefrigidarium was another circular pool (now at the Archaeological Museum at Naples) surrounding a fountain. It was flanked by two additional brick pools.[3]: 30–1
Thecaldarium was a circular room with marble floors and topped by a dome of almost 36 m diameter, close to the size of thePantheon's dome. The weight of the dome was carried by just eight masonry pillars. Between them were glass windows that helped heat the large room (and reduced the weight of the walls). Its seven pools measured 9.5 m × 5 m (depth of 1 m). Only six of these remain. The seventh was replaced by a small apse during the restoration by Constantine.[3]: 32–3
The Olympic-sizednatatio pool measured 50 m × 22 m. The walls rose to more than 20 m and the northern façade was structured by three huge columns made from grey granite. Between those columns were niches on several levels that housed ornamental statues.[3]: 33
Thenatatio was roofless with bronze mirrors mounted overhead to direct sunlight into the pool area. The entire bath building was on a raised platform 6 m (20 ft) high to allow for storage and furnaces under the building.[17]
Discovered in 1912 by Ettore Ghislanzoni, theMithraeum at the baths is considered the largest documented gathering space for the worshippers ofMithra, the Persian god in vogue with the military and mostly lower-class men, in the 2nd and 3rd centuries AD. The mithraeum was approximately 23 m (75 ft) long and 10 m (33 ft) wide with a cross-vaulted ceiling. It can be only roughly dated by the two main events associated with the baths: the mithraeum was created after the complex was completed circa AD 217 and it was probably no longer in use when the aqueduct supplying the complex was cut in the 530s.[1][19]
The floor of the main room was covered with a black and white mosaic. Benches lined the walls. A fresco portraying Mithra (or a torch bearer) is on the western wall. The only other ornamentation was a marble block, roughly carved into the shape of a snake. In the floor near the entrance a circular pit was found covered with a marble slab, with a terracotta bowl containing the remains of staves of wheat. A rectangular hole in the floor gives access to a small tunnel that runs under the center of the main hall into an adjoining room, where there is an entrance/exit with staircase. This, a unique feature in a mithraeum, has been controversial. Most scholars view this as afossa sanguinis, a ritual pit over which the bull at the center of the Mithraic mythology was slaughtered, bathing one or more initiates in its blood. Others think it was used as a sort of stage trap door allowing a person to stage a surprising entry into the room.[1][19][3]: 40–3
In a nearby room, a statue ofAphrodite Anadyomene was found in 1912. It is now located in the Museo Nazionale Romano at the Baths of Diocletian.[3]: 41, 43
Apart from housing the mithraeum, the tunnels served to heat the baths and as sewers for the outflow of water. They were also used to store the fuel for the furnaces – which are estimated to have burned around 10 tons of wood per day. Storage capacity had been estimated at more than 2,000 t of wood.[3]: 25
Overall, these tunnels ran for hundreds of metres underneath the main structure. They were lit by skylight-type windows that allowed the air to circulate, thus keeping the stored wood from rotting.[3]: 39
An underground water mill was excavated beginning in 1912. First thought to be medieval in origin it is now considered to date to Antiquity. It may have been a part of the original workings of the baths. Fire damage indicates it was burned in the 3rd century, but rebuilt with some alterations.[3]: 40
The 12 m (39 ft) columns of thefrigidarium were made of granite and they weighed close to 100 t (98 long tons; 110 short tons).
The baths were originally ornamented with high-quality sculptures, estimated to have numbered more than 120. Despite their location in one of the city's working class areas, of all the antique baths in Rome the Baths of Caracalla were found to have contained the most lavish assortment of statues. Although many were destroyed in the Middle Ages to make lime, beginning in the 16th century under Pope Paul III Farnese, sculptures were excavated from the area to serve as decorations in newly built palazzi.[3]: 47, 51
Among the well-known pieces recovered from the Baths of Caracalla are theFarnese Bull (probably from the easternpalaestra) andFarnese Hercules (from thefrigidarium), now in theMuseo Archeologico Nazionale,Naples; others are in theMuseo di Capodimonte there. One of the many statues is the colossal 4 m (13 ft) statue ofAsclepius.[3]: 47–8
Two granite tubs from thefrigidarium were taken toPiazza Farnese where they still serve asfountains, made byGirolamo Rainaldi. A granite column from thenatatio was taken to Florence byCosimo I de' Medici inPiazza Santa Trinita. It is now known as theColumn of Justice.[3]: 51 In the Lateran Collection of theVatican Museums are mosaics composed of rectangular panels depicting athletes, which were discovered in 1824 in two of the libraryexedrae to the east and west of the baths complex. They have been restored and are on display in theGregoriano Profano Museum.[20][21][22]
The Baths of Caracalla (and especially the centralfrigidarium) had a significant impact on the architecture of many later buildings. In Roman times, these included theBaths of Diocletian and theBasilica of Maxentius.[3]: 32
In the 19th and early 20th century, the design of the baths was used as the inspiration for several modern structures, includingSt George's Hall inLiverpool, the originalPennsylvania Station (demolished in 1963) inNew York City, the currentSenate of Canada Building in Ottawa, the interior of theHollywood Theatre in Portland, and the main hall of theUniversity of Leipzig (demolished in 1968).
The main halls of Penn Station, the Senate of Canada Building andChicago Union Station made use of direct copies of thefrigidarium's architecture.[3][23]
The central part of the bath complex (thecaldarium) was the summer home of theRome Opera company from 1937 to 1993. In 2001, use of the venue by the opera resumed but it now uses a temporary movable stage outside of the main structure, which reduces the stress on the antique ruins.[3]: 14
It is also a concert venue, having achieved fame as the venue and backdrop for the firstThree Tenors concert in 1990.
The area was used for theRome Grand Prix four times between 1947 and 1951.[24][25]
At the1960 Summer Olympics, the venue hosted thegymnastics events.
The baths were used as a filming location forJohn Wick: Chapter 2.
The extensive ruins of the baths have become a popular tourist attraction. The baths are open to the public for an admission fee. Access is limited to certain areas/walkways to avoid additional damage to the mosaic floors.
