The Amnya complex (Russian: городище Амня, romanized: gorodishche Amnya) is an archaeological site near the Amnya River in the lower Ob basin of western Siberia, dating to the early Neolithic and Chalcolithic. It comprises two sections, Amnya I and Amnya II, each a series of ten pit-houses of varying sizes about 50 meters apart. They are built atop a steep escarpment formerly overlooking a river, now adjacent to a series of peat bogs. Unlike Amnya II, Amnya I has significant defensive earthworks in the form of banks and ditches.
Although the region had been occupied since the Mesolithic, the first fortifications were built at Amnya I some time after 6100 BCE, preceding a main settlement phase for both sites for much of the 6th millennium. The houses were frequently destroyed by fire, linked to endemic violent conflicts in the region. Both settlements were abandoned before a period of reoccupation during the 4th millennium BCE.
Amnya I is one of the oldest known fortified settlements, as well as the northernmost Stone Age fort. Built by a hunter-gatherer population, Amnya I significantly predates the arrival of agriculture in the region. The sites were first excavated in 1987, with later excavations taking place in 1993, 2000, and 2019. A related Neolithic site, Kirip-Vis-Yurgan-2, has been linked to the Amnya culture due to similarities in recovered artifacts.
