This is one of the most significant sites in the Lower Vardar Valley which has been continuously excavated since 1977. The stratigraphy shows that there existed a settlement from the Archaic to the Roman period while near to the site there is an Iron Age necropolis. The Classical and the Hellenistic settlement occupied 6 hectares inside the fortification. The largest development of the town was during the 2nd – 3rd century when the public buildings such are the Temple of Heracles – Commodus and the so-called Palace were erected. In 268 the town was burnt by the Goths after which a new fortification was built. Besides the buildings, the material culture of the population is well- known from the discovery of numerous graves from the different periods of existence. One of the most interesting finds is the stadium stone with the distance between the ancient towns of Idomene and Doberos. Thanks to this find there is a scholarly dilemma of whether the town of Isar – Marvinci is Idomene or Doberos. The excavations in 2005 revealed 76 meters with four square towers of the fortification wall from the Late Antiquity and a vaulted building with unknown purpose called “Shrine”. The “Shrine” is partially damaged by the construction of the above-mentioned fortification wall. The interior is 3 meters high and there is a niche in the upper parts of one of the two walls. Next to the “Shrine” there are steps, a rectangular room and a channel. Inside the rectangular room there was discovered a hoard of bronze coins. Because of the damage made by the fortification wall and the unexcavated area around, at this moment it is impossible to understand the character and the function of the vaulted building. The only clear thing is that the whole complex belongs to the 2nd – 3rd century.
