Archaeologists associate it with the Sikhirta, a mythical people who allegedly lived on the peninsula before the arrival of the Nenets. Then the sikhirta were, apparently, partially assimilated, and partially exterminated by aliens and, by the beginning of the written history of those places (not earlier than the 19th century), turned from real people into heroes of Nenets legends.
According to them, sikhirta (abbreviated form - sirtya) were notable for their small stature, knew how to skillfully work bone, owned the rudiments of metallurgy. They lived underground - in the hills. They knew how to suddenly appear out of nowhere and just as suddenly and without a trace disappear. They did not breed deer, but they were skilled hunters and fishermen. They had a difficult relationship with the Nenets, they often fought, and the sikhirta were distinguished not so much by military valor as by their ability to quickly disappear. Then supernatural forces called the natives underground, where they live to this day, approximately like the Celtic fairies.
According to IA REGNUM, archaeologists managed to find the remains of a medieval settlement on the shores of Makarov Bay in the west of Taimyr, which could have once belonged to Sikhirta.
We found monuments from different times. They are roughly dated to the 7th-8th century AD and the 12th century. The first is a ritual-burial complex, where artistic items made of silver and bronze were discovered (a bowl made of silver and white bronze, probably of Iranian origin, Bulgarian silver, jewelry in the form of bronze loons and chain mail), and a settlement complex was found in Makarov Bay - a frame-and-earth building, which is a hill with an area of about 150 square meters, - said Danil Lysenko, General Director of Krasnoyarsk Archeology LLC.
The authors of the find consider the complex they found to be a similar settlement in the Nakhodka Bay (mouth of the Yenisei), surveyed by archaeologist Oleg Kardash in 2006. According to the report of O. Kardash, the walls of the building were a vertical set of poles. The inner space of the house consisted of two rooms: the central one, 3x5 m in size, and the gallery, 1, 2−1, 7 m wide, formed by the outer walls along the perimeter. A large open hearth was in the center. The floor of the house was lined with poles. The gallery, which framed the central room along the outer perimeter, served as a heat-insulating function and was obviously used for storing food, clothing and utensils. The outer walls could have been formed from sod-moss briquettes. As a result, the structure looked like an isolated hill overgrown with grass.
According to the results of dendrochronological analysis, the structure in the Nakhodka Bay was built at a time in 1220.
