Between the villages of Rasova and Dunareni, on a high hill on the right bank of the Danube, at the Musait point there is a fortification of the Scythian limes, with several development phases, having an uninterrupted evolution since the beginning of the 2nd century AD. until the first quarter of the 7th century BC. The Roman fort was built on the territory of a former Dacian fortress of the saci tribe, which seems to have been their capital. Roles,their leader, was an ally of Octavian Augustus. The name Sacidava is known from ancient literary sources and has been confirmed by epigraphic discoveries. Discovered and identified by Vasile Parvan, the fort was insufficiently researched, until 1969. Archaeological researches thus continued, with some interruptions, until 1980. In the last three years, little research has been made .
Sacidava had a rectangular shape, with 125m long sides, which enclosed about 4 hectars. The walls were about 2m thick and the towers were rectangular. The fortification was garissoned in in the second century by Cohors IV Gallorum, Cohors I cilicum sagittariorum milliaria, and later a vexillatio of the legion II Herculia de Troesmis (Iglita); later, in the IV-V centuries a cuneus equitum scutariorum lived here. A great fire and massive destruction happened during the third century, but the south of the fortification has not been reached. It was hypothesized that mid-century Gothic attacks were the cause of the destruction. In the fourth century there was a restoration of the enclosure on the western side and an extension of the fortress to the south by the erection of a new enclosure. The end of the fourth century is linked to a new massive fire. The fifth century is linked to repeated reconstructions,due to multiple fires. During this time numerous raids of the Germanic and Hunnic tribes took place in the area. The restoration and flowering of the fortress from the beginning of the 6th century are interrupted by yet another great fire, probably related to the kutrigur attack in 559. The next level of this century, with the reconstructions on the southern side of the enclosure, is dated in the second half of the VIth century. The last years of the fort took place between 602-620. Even after decommissioning the enclosure, a sporadic Roman-Byzantine dwelling was still occupied, which was later abandoned by the last inhabitants.
