A trial trench was dug in the western part of the “Columnar Hall”, allowing the discovery of the original dividing wall’s foundation: this large hall had been created by destroying this partition between two rooms of identical dimensions that adopted the module used in the 3rd century BC, subsequent to the foundation of the colony in 303 BC. These rooms on the forum are constructed according to the same module as the tabernae downtown; the same module is also used in the colony of Paestum. This trench also revealed the transformation of the back wall, cut back in order to allow the proportion of the “Columnar Hall” to become almost square, like a real Vitruvian Corinthian oecus. The laying of the mosaic floor seems contemporary with this huge makeover: the oecus was decorated with grand Corinthian columns which originally supported a vault covering the middle of the banqueting hall.

The portico in front of the “Columnar Hall” has been partially excavated; however, no further mosaic floor and no more fragments of the Fasti Albenses were discovered. A quadrangular structure in opus latericium (120 × 100 cm), found on the left side of the entrance of the room, may have been an altar or a statue base. A slightly larger than life-size marble hand and three of its fingers were found nearby. No traces were discovered of the column base of the portico colonnade corresponding to the original dividing wall. A complex structure of large architectural blocks was unearthed at the forum side of the portico (East); this structure probably sustained the weight of the higher placed portico and supported the steps leading to it.

The portico and its architectural link with the Via del Miliario and the forum still pose a problem: the situation differs from place to place. Only a complete clearing of the zone will allow us to better understand the situation.

The conservation team has worked on the largest plaque (AF.197.19-22) of the Fasti Albenses in order to have it displayed at the Museo Nazionale Romano (Palazzo Massimo alle Terme) during the exhibition Rivoluzione Augusto. L’imperatore che riscrisse il tempo e la città (16 December 2014 – 2 June 2015). New connections between fragments of the Fasti Albenses were discovered by Cesare Letta and Anja Stoll. Céline Devillers has continued her study of the figurative frescoes and Soline Delcros has made photogrammetric recordings of the main architectural elements (capitals and columns) and of the walls of both rooms.

Olivier Vrielynck and his team continued their exploration of the sewer system, mapping and drawing the different canals leading to the main drain. They have to date explored more than 140 m of them.
