The so-called "Villa of the Ambulatio" is ancient Roman residential-leisure complex in the coastal town of Baiae. The villa was previously mistaken for a large thermal bath complex due to its terraced structure, but later research identified it as a private residence.
The Villa of the Ambulatio is a well-preserved Roman villa that provides insight into the architectural and lifestyle elements of elite Roman residences. Originally constructed at the end of the 2nd century BCE or the beginning of the 1st century BCE, its current form primarily dates to the 1st century CE, as evidenced by the use of opus reticulatum in its construction. Its name, "Ambulatio", comes from the Latin term for a long, exedra-style portico commonly found in Roman villas, where wealthy owners engaged in promenades, reading, and leisure (otium). The villa is structured on multiple artificial terraces (basis villae), which descend toward the sea—a common feature in Roman coastal estates.
circa 80 BCE
The villa’s architectural layout is best appreciated by starting from the first terrace, located on the mountainside, which contained the residential area. A staircase to the north leads to a series of sitting rooms along the western side, featuring opus sectile or mosaic flooring and walls that were once clad in marble. Notable structures on this terrace include a large panoramic room, a peristyle, and an apsidal room at the southern end.
Descending to the second terrace, the ambulatio is located. Originally a foundational platform (basis) for the villa above, it was later transformed into a covered portico with two longitudinal naves separated by pillars connected by arches. A large rectangular room with an exedra and three niches on its lateral walls opens centrally along the western side of this level. The portico contains various architectural fragments discovered in the waters of the Port of Baiae, including marble decorations from structures linked to the Palatium of the Severan period (3rd century CE).
Further south, a staircase encircles the entire complex on its southern edge. Descending these stairs leads to the third terrace, now a garden. This level was likely another ambulatio, featuring pillars that once supported a vaulted covering. A centrally located room on the western side aligns with the grand halls of the upper terraces and a lower area, possibly a fountain.
Continuing down the south stairway brings visitors to the fourth terrace, characterized by two parallel corridors, above which a series of rooms open. These rooms are generally believed to have served as quarters for service personnel. The construction techniques used throughout the villa reflect various phases of building and renovation, indicative of its long-standing use and adaptation over time.

Abrahamic History & Archaeology is the study of history and archaeology with respect to the three Abrahamic Faiths without considering the religious and theological aspects. The goal of Abrahamic History is to understand how and why the religious doctrines and behaviours have evlovled and changed over time. Searching for patterns in the evolution of significant cultural events such as the development of farming, the emergence of cities, or the collapse of major civilizations for clues of why and how these have influenced the three major Abrahamic religions.
