ИСТИНА

According to dendrochronological data, the town of Ladoga was founded in the middle of the 8th century AD (Kirpichnikov, 1985). The Ladoga fortress and adjacent ancient settlement are found near the inflow of the Ladozhka River into the Volkhov River. Under the habitation deposits, two buried soils were described. These soils are separated from one another by the 30- to 80-cm-thick layer of sapropel deposited during the Ladoga transgression. The upper soil has a distinct plow horizons; the charcoal found in this horizon has the radiocarbon age within the interval from 1415 ± 90 to 1480 ± 140 BP (Ki-17316, Ki-18445). On the surface of the lower soil under the sapropel layer of the Ladoga transgression with a maximum about 3–4 ka BP, habitation deposits of the Neolithic Age were found in the area of the Ladozhka mouth. The humus from this soil has the radiocarbon age of 4560±70 BP (Ki-18100).
