San Pietro is the main archaeological site in Bari, together with the adjacent complex of the Monastery of Santa Scolastica, located in one of the city’s oldest areas, with documented settlements dating from the Bronze Age to the 1960s. Archaeological research reveals a history of stratification. Over the centuries, the San Pietro area has hosted various configurations and functions: initially a place of worship—a Romanesque church dating back to the 12th century—later a Franciscan convent. At the beginning of the 17th century, the church was significantly expanded, and in the 19th century, it was converted into a civic building for educational use, then into a Consortium Hospital, a place of care, which was demolished in 1969 due to the extensive damage suffered during the World War.
The artistic project, which reinterprets the architectural volumes that have shaped the area over the past thousand years, follows the traces of past structures to create a new and original space for the city, in continuity with its path of renewal and meaningful symbolic heritage. The intervention as a whole formally expresses the stratification of the various historical periods that have shaped the site, unfolding as a progressive sequence of architectural forms enclosed within one another, and offering a snapshot of a process that reveals the heterogeneous nature of both personal and collective heritage.



San Pietro in Bari is an ancient place that has never stopped evolving. It is a fragment of the city that, over time, has witnessed different forms of life, thought, and the sacred. Here, matter has been shaped and unshaped many times; each time, a passage, a transformation. Each time, a human gesture that left a mark. All these changes reflect the evolution of the city and the way people have lived in and understood this place.To build, to destroy, to rebuild, like a breath. Layers upon layers, rooted in the same small patch of earth that, over the centuries and in different forms, has been a house of worship, a place of ritual, a keeper of the sense of the sacred as seen by the city and its people.Building San Pietro is an act that returns and, in a way, asks us: who are we? What do we value? What does the sacred mean to us? This place is an open dialogue between what we once were and what we are, a quiet question that accompanies the city as it continues to evolve.



Facing the past takes us to another place, where we may find or lose ourselves, recognize or miss who we are.
In the search for historical evidence, we weave traces and fragments of memory to piece together, as far as possible, an image of what came before us. We turn to the sources and documents we have carefully preserved, aware of how few certainties they offer and how large the gaps that remain.
When the truth of history is beyond reach, curiosity turns to what is missing. We allow ourselves to be drawn to uncertain data and distant recollections, where forms are no longer fixed but appear as almost unconscious, almost oracular impressions that surface from oblivion.
The past is not a territory to be mapped with precision but an undefined, contemplative space. It is an inner dialogue, an encounter that does not seek certainty but embraces the multiplicity and ambiguity of things.


The city has a living body that holds us within it. It takes shape and meaning, gains and loses value, moving through cycles of decay and renewal in a dance we all share. We are made of the same matter.
Archaeology follows that matter, studying, listening, and observing it through a practice guided by care.
Through that gaze, the city reveals itself in a shard of pottery, a sliver of glass, a coin, but also in a tooth, a scrap of fabric, a trace of plaster, each fragment becoming part of the shared memory it keeps alive.



Some traces are so essential that they slip beyond the surface of things. They vibrate beneath what we see, revealing the hidden pattern that gives form to the world.
Each person carries the memory of others and becomes part of a tradition that reaches beyond the self —a conversation that stretches across centuries, where every life continues those before it while shaping its own unique presence.


What remains reveals a landscape shaped by what is absent.
Can there be an archaeology of loss? To explore what is missing is to accept absence as part of history, acknowledging that not everything can be recovered and that every attempt at reconstruction carries an element of mystery. It is an approach that seeks meaning rather than completion.
It is a practice that honours what has been left out and what has fallen silent, recognizing that even what can no longer be seen still belongs to us. It speaks to the sacred, to the idea of transcendence, and to the enigma that lingers behind all that is lost and unfinished.

Edoardo Tresoldi’s artistic intervention is part of the project to enhance the Archaeological Area of San Pietro and the Archaeological Museum of Santa Scolastica, promoted by the Ministry of Culture and realized, with the support of European funds, under the coordination of the former Regional Secretariat of the MiC for Apulia, directed by Arch. Maria Piccarreta, and, following ministerial reform, by the Superintendency of Archaeology, Fine Arts, and Landscape for the Metropolitan City of Bari, headed by Dr. Francesca Romana Paolillo.
The design and execution of the project rely on the expertise of a working group composed of the Sole Project Manager and the architect. Donatella Campanile, Designer and Works Director, arch. Francesco Longobardi, and Scientific Director and Co-designer, Dr. Ebe Chiara Princigalli. The project management team was completed by Dr. Dario Ciminale, responsible for collaborating with the Scientific Management during the design and execution phases, Dr. Marisa Corrente, who collaborated with the Scientific Management during the design phase, and arch. Annalisa Cascione, Collaborator with the Works Direction, and arch. Marco Silvestri, Safety Coordinator. Arch. Arturo Cucciolla provided a valuable contribution focused on the historical, urban, and architectural aspects.
