During the Palazzo Mazzetti restoration project (2005 – 2010), Piedmont’s Archaeological Heritage Department led an excavation whose results are now visible in the cellars.

In addition to the ceramic fragments, small objects and coins ranging from the time of the founding of Hasta (late 2nd century BC) to the 16th century, structures from the Roman era and Middle Ages were also brought to light, offering proof of the city’s archaeological layers.

The discovery of Roman walls and paved floors suggest that the area where Palazzo Mazzetti was built was the eastern edge of the Forum, the heart of the old city.

The Dark Ages, on the other hand, are characterized by precarious (clay or wood) structures that enclose small environments that were probably workshop-dwellings alongside burials. The Medieval period is clearly denoted by traces of buildings with square towers partially overlooking Corso Alfieri (the ancient Cardo Maximus).
