The hillfort is situated on the northern edge of the high plateau that dominated the river valley. It is surrounded by an earthen rampart near 3 m high on the southern part and up to 1 m high on the eastern part. Besides that, a deep ravine with spring runs alongside the eastern rampart of the hillfort. Northern and western parts of the hillfort were destroyed in the early 20th century while constructing the railway and a quarry. The modern square of the hillfort is near 5.1 ha.

Joint Ukrainian-Polish archaeological expedition started to explore Severynivka hillfort in 2009 after more than a half-century pause in the monument’s study.

The first task was examining the hillfort fortification. An exploratory trench was dug out on the SW part of the hillfort where the rampart ended at the edge of a precipice. Four non-simultaneous ditches with four subsequent layers within the rampart allows outlining four periods of the building. The earliest rampart was erected on the clayey soil with no cultural debris being found under it. The second period is distinguished by a stone pavement on the inner slope on which a fireplace was placed. Besides that, remnants of the wooden palisade were traced on the bottom of the second ditch. The layers of the third and fourth periods were partly destroyed by erosion and WW2 trenches. However, one can say that the latest ditch reached 4.05 m deep. And a layer made of big stone boulders was traced on the inner slope of the rampart’s fourth period. Unfortunately, no wooden structure was traced within the walls.

Also, a small prospective trench was dug out on the NW part of the hillfort at the edge of the precipice. A dwelling, harshly destroyed by erosion, was explored on this excavation site. It is distinguished by numerous finds of the Early-Scythian handmade pottery. Besides that, a children pair burial was found in the half-dumped basement of this dwelling, covered with cultural debris. Anthropological analysis showed that they suffered from diseases and died at a young age.
