Capo di Bove

Capo di Bove is an archaeological site located on the Appian Way on the outskirts of Rome, Italy, roughly 500 meters from the Tomb of Caecilia Metella. It preserves the thermal baths of a vast Roman property owned in the second century AD by the prominent Greek senator Herodes Atticus and his wife Annia Regilla. The site provides significant insight into elite private bath complexes of the period, featuring well preserved mosaics and sophisticated heating infrastructure. Today it operates as a publicly accessible monument within the Appian Way Regional Park.

The baths on the property date to the mid second century AD and remained in use until at least the fourth century. The medieval name Capo di Bove, along with the associated Capo di Vacca, derives from the sculpted ox head decorations on the nearby Tomb of Caecilia Metella. In 1302, Cardinal Francesco Caetani, nephew of Pope Boniface VIII, purchased the estate and built a castrum near the mausoleum. During the 17th century, the area functioned as a hospital under the Ospedale del Ss. Salvatore ad Sancta Sanctorum, and in the 19th century it came under the control of the monastery at the Basilica of Saint Paul Outside the Walls. The land was used for agriculture, specifically grape growing, until the post World War II era. The Italian government acquired the property at 222 Appian Way in 2002, leading to excavations that uncovered the Roman remains.

The site's primary historical scope centers on its second century thermal bath complex, which was almost certainly for private use. The surviving architectural and decorative elements reveal a highly elegant environment equipped with the standard rooms of Roman baths: a caldarium, a tepidarium, and a frigidarium. Water for the complex was supplied by two large cisterns. The heating system was supported by underground ovens, known as praefurnia, which were stoked with wood. Hot air circulated through hollow spaces, or hypocausts, created by laying 60 by 60 centimeter tiles on brick pillars called pilae. Additional heat was distributed through narrow wall tubes, or tubuli. Greek inscriptions found at the site attest to the Greek origins of Herodes Atticus. An internal exhibition displays photographs of the Appian Way from the first half of the 20th century.

Among the most significant physical remains at Capo di Bove are the well preserved mosaics and the high quality building materials used throughout the baths. The site retains its sophisticated heating infrastructure, including the hypocaust pillars and wall tubuli, which were originally covered with marble or painted plaster. Other notable features include the Greek inscriptions referencing Herodes Atticus, bronze heating devices positioned directly above the ovens, and a complex drainage system designed to remove excess or polluted water. The baths also included a laconicum, or sauna, and a sudatio, a massage room.

In addition to the ancient ruins, the site includes a former farmhouse, or casale, constructed atop the Roman cistern. Between 1943 and 1945, the previous occupant converted the farmhouse into a residential villa. This building incorporates numerous Roman ruins into its walls, including original pipes from the baths that are built directly into some of the windows. Following the 2002 government acquisition, the casale was repurposed to serve the archaeological area.

Capo di Bove is located at 222 Appian Way in Rome. The excavations can be visited daily free of charge. The converted casale now serves as the information point for the archaeological area and hosts exhibitions and cultural events. Since 2008, the building has also housed the Archivio Antonio Cederna. The site is managed by the Parco Archeologico dell'Appia Antica.
