The excavation campaign, with the participation of students from various universities, took place between 12th July-13th August 2010. The investigations concentrated on trenches M, N, R and T, obtaining results which clarified certain aspects relating to the site’s earliest phases and confirmed that it is the site of Fanum Voltumnae.

Trench M was extended to the south: a first layer covered the entire area, dating its definitive abandonment to the 8th-9th century A.D. on the basis of the Forum Ware found within it. Below was a layer containing a substantial amount of material, the dating element being African Red Slip ware. Among this material was a marble sundial and fragments of a terracotta statuette, perhaps identifiable as Artemis. The extension made it possible to check the line of the temenos wall which had undergone rebuilds in distinct periods. In the same trench, in the sector between the temenos, donario built of trachyte and a monolithic tufa altar the edges of a rather irregular pit were identified. It was divided into two sectors by a well-constructed feature of reused medium sized stone fragments. The pit was filled in the Augustan period with materials dating from the end of the 6th century B.C. to the late Republican period.

In trench N the excavation aimed to trace the continuation of the monumental bases of a building situated in the trench and to examine the nature of the cassone built of tufa slabs adjacent to it. In the interior of the building a floor level was uncovered, on which there was a layer containing a large amount of pottery: cups and small plates in Attic and Etruscan figured pottery and fragments bearing inscriptions of a cult nature. The tufa-built cassone was perpendicular to the southern base of the building and its covering blocks had funnel-shaped holes for libations in them. Inside below a uniform layer of silt was the skeleton of an infant about three years old, which had probably been buried in a wooden coffin. Two artefacts were found in the tomb, a grey ware ladle-dipper and the foot with stamped decoration from a black glaze cup, purposely broken. Up against the southern edge of the burial was a small, coarse ware jar closed by a black glaze cup. It contained burnt bones.

In trench R the caldarium was examined. Below layers of collapse occupation layers attested the use of its rooms in the 4th-5th century A.D. as a temporary residential structures. The second room investigated, north of the apsidal pool of the caldarium, revealed the collapse of the flooring and of the heating structures which filled the hypocaust. The latter had walls faced with tiles lined with opus signinum. The tile lining terminated directly above the floor of the room which was made of similar tiles, on which the square bricks of the suspensurae rested.

A new trench (T) was opened with the ain of intercepting the continuation of the walls of the imposing Etruscan building in tufa blocks, partially uncovered in trench N. In the central-western sector of the new trench a stretch of road came to light, built of small cobbles. The chronological contemporaneity of the Archaic cobbled surface found in trench N, below the early Hellenistic basalt paving, appeared to be confirmed by the materials found and the exact correspondence of the levels at which they appeared.
