This burial site, discovered in the 19th century, once included 78 mounds, some of which were damaged or destroyed in the 20th century due to construction. Excavations revealed that beneath the mounds lie Slavic burials from the late 12th and 13th centuries, belonging to the Vyatichi, a tribe that inhabited the Moscow River valley and the territory of modern Moscow.

The Vyatichi, who left the Spas-Tushino burial mounds, followed the burial customs of their ancestors, which included creating a burial mound over the grave site. In the 12th-13th centuries, there was a transition from pagan traditions to Byzantine-style Christianity, which influenced the burial rites of the Vyatichi. For example, in the mounds of the Mitino park, it can be seen that the deceased were buried with their heads facing west, as is customary among Orthodox Christians, and sometimes placed in shallow graves. However, pagan customs, such as the construction of mounds and ritual bonfires, remained. The tradition of placing personal belongings of the deceased in the grave also persisted, which helped archaeologists identify the burials as belonging to the Vyatichi. Among the finds were ornaments characteristic of this tribe.

Archaeologists discovered five-lobed and seven-lobed ear rings, bronze twisted neck rings, pendants, bells, rings, bracelets, glass and carnelian beads, as well as household knives and clay pots in the mounds.

The Vyatichi, distinct from other East Slavic tribes, formed a tribal union and inhabited the Upper Oka region, controlling important trade routes. They lived in a clan-based society, elected a leader known as a prince, and led a semi-hunting, semi-agricultural lifestyle. The Vyatichi engaged in agriculture, hunting, beekeeping, and fishing, raised livestock, and actively traded with the Arab world, Western Europe, and Byzantium.

Archaeological excavations revealed workshops of metallurgists, blacksmiths, jewelers, and other craftsmen. Metallurgy was based on local ores, and jewelry-making reached a high level, second only to Kyiv. Craftsmen produced a variety of ornaments and household items.
