The investigations at Stobi in 2012 were carried on five locations: the Temple, the Theatre, the Episcopal Basilica, the West Necropolis and the Semicircular Court.

The excavations in the temple area continued to the north and south of the building. The north side (in front of the steps of the temple) yielded the most significant discovery. Many architectural elements of the building were found on a use level from the 5th century. Besides the pediment and architrave blocks, an oversized marble sculpture of Isis was unearthed, revealing the deity to whom the temple was devoted. The sculpture was found almost 40 years after the discovery of an inscription that mentions a sacrum Isidi in Stobi. The head and the hands of the goddess are not preserved, while the rest of the sculpture exceeds the length of 2 metres. Judging by the style and the resemblance with the Isis in the Capitoline museum, it probably belongs to the Hadrianic era. The altar was found just below the sculpture, on the original use level of the temple. Two bases for statues or inscriptions were found to the west of the steps. A sacrificial pit with several ceramic flasks was found on the south side, in front of the entrance to the subterranean chambers.

The excavations of the Theatre were focused on the eastern half of the ima cavea. The goal was to explore the space between the radial walls in order to understand the process of construction and prepare the area for conservation. Red lines and roman numerals were discovered on the walls, marking the sequences of construction and the successive deposit of soil between them in order to create an artificial terrace. The central radial corridor and the two rooms on each side of the corridor were excavated as well. These parts of the theatre were used even during the late antiquity and were incorporated in the newly built houses. The most significant discovery is that the two rooms to the east and west of the radial corridor served as exits with stairways that led to the central box of honor.

The layers below the nave of the Old Episcopal Basilica were excavated in order to reveal the history of the area and prepare the terrain for a new bedding of the mosaic, removed due to conservation. Layers with material from the Late Hellenistic and Augustan period reveal that in a certain period of time there were modest houses which were leveled before the Old Basilica was constructed. No remains indicating that the church was preceded by domus ecclesiae were found.

The rooms of the complex surrounding the Semicircular Court, to the west of the Episcopal Basilica, revealed material from the second half of the 6th century. Judging by the finds it could be presumed that they mainly served as workshops and stores in the last years of the existence of the city.

47 graves were excavated at the Western Necropolis. The most interesting discovery is the grave of a soldier from the 1st century BC. The deceased was buried with his iron spear, wooden shield with a bronze conical umbo and an iron dagger. Among the finds there was a small bronze application with an eight rayed star.
