It is located in the northern edge of Opishnia village, Opishnia Village Council, Zinkiv district, Poltava region, in Kardashiv Val natural landmark, 6 km to the south of Velyke Bilske fortified settlement.

It was surveyed by V.H. Liaskoronskyi (early 20^th c.); archaeological researches (excavations) were carried out by I.I. Liapushkin (1940), H.T. Kovpanenko (1950), later it was inspected by employees of the Poltava Museum of Local Lore and the National Museum-Reserve of Ukrainian Pottery. In 2001-2002, the excavations led by A.V. Heiko were carried out on the fortified settlement.

The Scythian fortified settlement occupies a long narrow cape on the right root bank of the Vorskla River.

The ancient inhabitants chose the central part of the cape for settlement, separating it with a moat and a breastwork (up to 2.0 m high). An escarpment of 6-11 m high can be traced on the fortified settlement in the southern and south-eastern and south-western parts.

The moat was crossed in the south-eastern part of the fortified settlement. Three moats operating at different times of the fortified settlement’s existence are partially traced. Hence the bronze arrowhead of 5th-4th cc. BC was found here.

In 2001-2002, the moat was excavated.

The excavated area was established in the fortified settlement itself. Another moat was revealed on its southern edge, which is located on the site of the cape. The width of the excavated moat is 6.9 m. The depth is 3.68 m. The remains of a large fire can be traced in the moat filling.

This fortified settlement was part of several Povorskla fortifications, the centre of which was Bilske fortified settlement.
