Already investigated in 1989-90 and 1992, the area was systematically explored by the Post-graduate School of Archaeology, Padova University in 2001. A vast monumental complex was identified, which to the south comprised a large open space, probably a garden, surrounded by a portico with a large exedra placed on the main axis. To the north was a building characterised by a long façade with portico and numerous groups of rooms, linked by covered walkways. It is difficult to define the function of this complex: it may be suggested that it was a rich private villa and perhaps the structures should be placed in relationship to the imposing baths found by the Veneto Superintendency below the Hotel Terme Neroniane. The finds collected and the stylistic analysis of the floors give an Augustan-Tiberian date.

Two areas were opened, one at the northern end of the area under investigation (Trench P), the other more centrally placed, in correspondence with the sector already partially examined by the 1989-90 and 1992 excavations (Trench S). Trench P revealed a group of very refined and rich residential rooms, as attested by the floor typology, architectural materials and plaster fragments collected in the layers of collapse-abandonment. All that remains of the walls are the robber trenches made after the abandonment of the building, whilst the floors are well preserved.

The hub of the complex seems to be a vast hall (circa 120m2 ) situated on the same axis as the southern exedra and characterised by an elegant inlayed pavement of small black and white marble slabs arranged in two decorative motifs: one of triangles, hexagons and rhombi, the other of squares and rectangles. Other rooms of varying sizes opened off the side of this hall in a symmetrical arrangement, with pavements in black and white mosaic or inlayed coloured marble from the Mediterranean basin. In Trench S other rooms were uncovered, some of which datable to between the end of the 1st and beginning of the 2nd century A.D., attesting that the complex underwent reconstruction. That the two largest rooms were heated is shown by the small pilasters that must have supported the floor. Many fragments of sculpture, antefixes that decorated the top of the roof, stucco cornices, and plaster painted with pigments that came from Egypt were found.
