The 2004 excavations continued with the project begun in 2003, a collaboration involving the Archaeological Superintendency of the Marche, the University of Macerata, and the administrations of the town of Sant’Angelo In Vado and the province of Peasaro and Urbino. Using archive plans and photographs, the excavation followed the edge of the 1957-59 excavations, the western section of the bath building, uncovering a vast section of the west wall of a large heated room with hypocaust and the opening of a large central well. Excavation halted at the level of the make up for the hypocaust floor.

At the same time as work continued in the bath building, a deep trench, 13 m long and 1.40 m wide (Trench north cardo) was dug which followed the road drain below the garden of the Amadio property. Following the mechanical removal of the top soil, the excavation identified four phases dating to the antique, late-antique, post-antique and modern periods. The original construction of the road was dated to the early imperial period. At the end of the season, the trench was back filled.

During the excavations both ancient and modern archaeological material was found (flints, black gloss, Italian sigillata, thin-walled ware, glazed and majolica pottery). The investigation was run as a training excavation for the archaeology students of Macerata University.
