A short excavation campaign undertaken along the viale dei Platani, better known as viale Ferrovia, partially investigated a large complex of public buildings, probably identifiable as the market of ancient _Teanum Sidicinum_. Two groups of structures were identified, probably with related functions, situated on different levels of the bedrock and sloping slightly to the south. These were obliterated in the medieval period by substantial alluvial deposits. In the western area, stood a large building probably dating to the early imperial period. Built in _opus reticulatum_, it was divided into large spaces and restructured (in _opus mixtum_) during the various occupation phases (from the second half of the 1st century A.D.- 2nd century A.D. It probably functioned as an _horreum_. On the basis of a hoard of _denarii_ of imperial date, found in a destruction layer, it appeared that the structure ceased to be used between the 2nd-3rd century A.D. The north-eastern area revealed the levelling of multi-stratified structures which seemed to cover the entire chronology of _Teanum Sidicinum_, as attested by previous excavations. A structure of tufa blocks resting directly on the tufa bedrock and comprising several rooms was succeeded by the _opus reticulatum_ building and later obliterated by the foundations of a large octagonal structure. The latter comprised two concentric elements of which four sides were identified, connected to a system for the drainage of water. This structure may be identified, with due caution, as the tholos of a _macellum_. The positioning of a market area and warehouses on this site would fit well with the proximity to the edge of the residential zone, although still quite close to the acropolis and to the zone where entertainments were held. It would also fit in with the finds (both systematic and chance) from the areas on the edge of the corso during the second half of the 20th century.
