After a break of some years, the University of Perugia resumed archaeological research at Gubbio in the Roman quarter of the Guastuglia.
The excavations were directed by Prof. Gian Luca Grassigli, in agreement with the local authorities and the Archaeological Superintendency for Umbria.

The area chosen for the investigation, a 20 × 20 m square, was situated immediately south of the so-called Domus del Banchetto (about 10 m away), in a slightly raised area that had not been previously investigated. The excavations uncovered a vast complex formed by four rectangular rooms, whose investigation raised many questions and provided important evidence for the historical and planimetric reconstruction of the building.

At this stage in the research, it is possible to distinguish several occupation phases and internal restructuring, strictly connected to the historical monument’s main developments.
The latest phases were attested by levels showing sporadic occupation. The structure was divided into four rooms each characterised by layers with a soil matrix containing materials that varied both in type and date.

The second occupation phase, characterised by the presence of four distinct rooms, presented specific peculiarities, with clear evidence of restructuring and spatial reorganisation. At this stage of the excavations, the plans of rooms 1 and 3 appear to have remained unaltered, while room 2 was reduced in size. In fact, wall USM 14 = 15 was built on an east-west alignment at a right angle to walls USM 11 and USM 13 in order to create a closed quadrangular room in the southernmost part of the complex. A threshold, US 27, for the entrance into this room was built on wall USM 16, the southern wall of the room.

In phase III, the layout of the structure appears less organised. Room 3 remains unchanged, while rooms 1, 2, and 4 become one large room bordered to the west by wall USM 13 and to the south by wall USM 16, with a central dividing wall, USM 11.
The floors were formed by an earthy-clay matrix and compact cobblestones.

In phase IV, the plan remained unaltered, only the floor levels changed.
