The excavation campaign that took place in May-June 2022 led to the exhaustion of the archaeological deposit in much of the essay begun in 2019. The investigation of a portion of the monumental terrace which is configured as an imposing block wall was completed squared preserved for approx. 2 meters high, in which a channel opens for the outlet of the water coming from the rooms above. The finds found in the layers to be related to the construction of the terrace seem to date back to the fifth century. to. C. The room located on the terrace, whose investigation was begun in 2021, is configured as a rectangular room open on the south side. Numerous interventions of reconstruction of the walls, unfortunately poorly preserved, and the presence of at least two clearly distinct phases, allow us to postulate an extended use over time. The materials found are preliminary dated between the V / IV and the II century BC. C. Between the second and the beginning of the first century B.C. the area is finally abandoned and the remains of the buildings thrown south of the terrace.

The function of the structures found is still unclear, as is its relationship with the lagoon. Whether the abandonment of infrastructures is linked to the change in the extension of the lagoon is one of the questions that the research project intends to answer with future campaigns.

The excavations are carried out under ministerial concession and in cooperation with the Municipality of Castiglione della Pescaia (GR).
