Vitruvius Steps Out of the Page: The Only Building by Rome's Great Architect Comes to Light in Fano

For two thousand years, the Roman architect Vitruvius has been known almost entirely through his words. Now, for the first time, the world can point to a building and say with real confidence that he designed it. In the coastal town of Fano, on Italy's Adriatic shore, archaeologists have identified the remains of the only structure that can be firmly attributed to him.

The architect who wrote the book

Vitruvius is a towering figure in the history of architecture, yet a strangely elusive one. His treatise, known as De Architectura, shaped how Europeans thought about building for centuries, influencing the masters of the Renaissance and still quoted in classrooms today. What he had actually built with his own hands, however, had long remained a mystery.

In his own writing, Vitruvius described a basilica he had designed in the town of Fanum Fortunae, the Roman ancestor of modern Fano. Generations of scholars debated whether any trace of it survived, and where exactly it might lie. According to reports on the excavation, the new findings now appear to settle that long-running question at last.

A discovery beneath a town square

The structure came to light beneath Piazza Andrea Costa, one of Fano's central squares, during rescue excavations carried out ahead of a planned urban redevelopment. The work is tied to a wider project financed through Italy's National Recovery and Resilience Plan, the funding programme widely known by its Italian initials as the PNRR.

Dated to the late first century before our era, the remains reportedly match the detailed account Vitruvius left behind with a precision that astonished the specialists involved. It is that close correspondence between the ancient text and the physical ruins in the ground that gives archaeologists such unusual confidence in the attribution.

What the excavation revealed

The basilica was laid out as a large rectangle, framed by eight columns along its longer sides and four across the shorter ends. On-site measurements indicate the columns were substantial, roughly five Roman feet across, close to sixty inches, and are thought to have risen to a height of around fifteen metres above the floor.

During the most recent season, the team uncovered the base of the sixth column on one side, although it was found partly damaged. They also exposed Roman floor levels, traced a previously unknown stretch of wall along Via Montevecchio, and identified the curved remains of an apse-shaped wall in the central area of the site.

Layers of a longer story

As is so often the case in Italian towns, the basilica did not exist in isolation. Investigators found evidence that the building was renovated in the second century of our era, including the use of marble brought from the Peloponnese, a clear sign of the wealth and the connections that once flowed through this Roman port.

Later layers tell of a long afterlife. Ceramic fragments dated to the eleventh and twelfth centuries document how the site was reused in medieval times, while traces of earlier structures beneath the basilica suggest the ground had already been built upon well before Vitruvius ever set his own plans down there.

Money, restoration and what comes next

With the first phase of investigation now concluded, attention is turning to conservation. According to the reports, the municipality and the Marche region have each committed around two hundred thousand euros, while the Ministry of Culture has allocated a further three hundred and fifty thousand for restoration and continued study of the site.

A larger request, of some eight hundred thousand euros, has reportedly been submitted to keep the excavation going in the seasons ahead. The results of the work so far are expected to be presented at the Mediterranean Archaeological Tourism Exchange in Paestum, held between late October and early November of this year.

Why it matters

As the archaeologist Cristiano Casci Ceccacci put it, the discovery of the Basilica of Vitruvius represents a heritage of extraordinary scientific and cultural value, one that clearly deserves much further study. For a small Adriatic town, it is also a rare chance to place itself firmly on the map of the ancient world.

Beyond the columns and the careful measurements lies something rarer still. In the ruins under a modern square, theory and practice finally meet, and the man who taught the West how to write about architecture can at last be seen as a builder in his own right. For Fano, and for anyone who cares about antiquity, that is a remarkable thing to witness.
