After a year’s break from the pandemic, a caroggi campaign and an excavation campaign took place in 2021 as part of the research project. The core drilling campaign, carried out in collaboration with the Institute of Geographical Sciences of the Free University of Berlin, made it possible to carry out a further twenty cores, many of which returned sediments of ancient calm waters, even several meters long. These findings made it possible to delineate in more detail the extension of the Prile lagoon near the site under excavation and the Etruscan city of Vetulonia.

The archaeological excavation involved a section of the monumental terrace and an environment located north of it, thus continuing the investigations begun in 2019. The terrace is preserved in height for at least four rows of square blocks. The structure was probably built during the Etruscan-Hellenistic period (4th-3rd century BC). A series of tiled roofs opened onto the terrace, the function of which is not yet clear. In the environment investigated, the materials mainly refer to the third century BC. C.

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