The small performance building on the hill of Santa Teresa was discovered and excavated in the late 1920s. Restoration works date back to the years of the Second World War and the fifties of the twentieth century. Given its small size, the theatre presents all the typical elements of this class of buildings: the cavea, supported by radial wedges in mixed work, is equipped with an annular median corridor covered by a barrel vault at the ends of which are the side entrances (parodoi) to the orchestra area. A third vaulted entrance is placed in the middle position. The stage area (proscenium) is a pit with space to hold theater machines and curtains. The scene is equipped with three canonical doors and rear stairs that allowed actors to climb to the upper levels. A series of bases of columns still in place indicate the presence of the porticus post scaenam. In the late ancient age, after the abandonment of the structure, the vaulted corridors were occupied by at least three furnaces for the firing of terracotta products.
