The 6th excavation campaign on the site of Castellina-Vetricella mainly concentrated on the management of several stratigraphic elements that emerged during the previous campaign and on the extension of the excavation area. In fact, the main objective was the removal of several partially investigated contexts (mainly situated in sectors III and IV) and the opening of new areas through the removal of the layers of humus/agricultural soil (in order to facilitate new excavations next season).

Excavation in sectors I/II were suspended in order to achieve a more coherent view of the context to which the exposed elements belong, in particular those relating to the first occupation phase.
In sector III, the layers inside the previously identified rectangular structure were removed, which constituted a floor surface delimited by the foundation trench. This stratigraphy had already been identified and analysed during previous campaigns and its removal exposed a level of soil with a sandy matrix, apparently natural.

In the south sector, the excavation area was extended towards the south for about 3 m, removing the agricultural layer and halting the excavation at a level that did not correspond with any elements of the ancient stratigraphy, in order to preserve the underlying deposit until subsequent excavation.

In nearby sector IV, the fill was removed from several postholes. It was mainly constituted by friable soil with a sandy-silt matrix, containing charcoal and stones. As in sector III, the excavation area was also extended towards the east and south. In this case, the strategy was to prepare the area for the subsequent excavation of two sections of the site that could potentially reveal evidence of the structures present outside the city wall. In fact, the extension of the excavation aimed to investigate both in the direction of nearby sector III (they will eventually link up), and in the direction of what aerial photographs suggest was the entrance/access to the ditch surrounding the settlement.
