Four distinct occupation phases were excavated. The latest (2001-2005 excavations), datable to the beginning of the medieval period, was characterised by the remains of a house with several rooms, facing onto a very well-preserved basalt paved road.

The other three phases dated to the late Republican period (mid 1st century B.C.); the early Imperial period (Julio-Claudian era, beginning of the 1st century A.D.) when the area was monumentalised; the mid Imperial period (reign of Hadrian, around the mid 2nd century A.D.).

At the present stage of the excavation the best known phase is that of the early Imperial period. This was the phase of the monumental portico (22 × 20.85 m), whose materials were removed in the medieval period to be reused in other constructions. Inside the portico there was a drainage channel made of monolithic blocks which delimited the complex.

The investigations inside the area delimited by the drainage channel (2007-2008) revealed the foundations of a temple which constitutes the first urban cult building in Gubbio to be extensively explored. The temple was 7.40 × 11.59 m, with the entrance opening towards the south-east. It was divided into a cella, 7.40 × 6.75 m, preceded by a pronaos with columns, 7.40 × 4.84 m. Only the opus caementicium foundations remained. The conglomerate had been poured into shuttered trenches and the negative impression of the timbers was clearly visible. Nothing remained of the temple walls apart from a fragment of a moulded pedestal made of hard local stone, 2.00 × 0.80 m high, found in a pit by the foundations. The hypothesis that this was a cult building is supported by the discovery in front of the entrance of a votive deposit relating to the construction of the entire complex. This deposit, sealed by a double layer of stones and tile, contained remains of a meal (bone and charcoal), pottery cooking wares and other materials including lamps, amphorae, fine table ware and miniature vases. The study of these materials and the stratigraphical evidence dated the building to the beginning of the 1st century A.D.

In 2009 two trenches (10 × 10 m) were opened in the south-eastern sector of the area, close to the eastern corner of the portico. The excavations identified a paved road presumably datable to the beginning of the 1st century A.D. The road, on which cart tracks were clearly visible, was paved with large irregular basoli made of local hard stone. It skirted the north side of the portico and delimited the area of the sanctuary. Future excavations will explore the southern sector of the site with the aim of making a definitive plan of the sacred area.
