The Tiya Archaeological Site is located in central Ethiopia, 85 km south of Addis Ababa, in the vicinity of Tiya. Of the 160 archaeological sites discovered in the Soddo region, Tiyya is considered the most important, in 1980 it was included in the UNESCO World Heritage List as the most representative remnants of ancient Ethiopian culture. The archaeological site of Tiyya consists of 36 huge stone monoliths, including 32 steles with images of swords and other mysterious signs and symbols carved on their surface, most of which have not yet been deciphered. Monoliths with a height of 1 to 5 meters have a different shape - flat, conical or round. Who created these steles, for what purpose and at what time - is not established. During archaeological excavations, skeletons of people who died in battle were discovered, their age varies from 18 to 30 years. Scientists suggest that steles could appear in the period from the 11th to the 13th century, their most likely purpose being tombstones at the mass graves of soldiers who died in battle. To date, the most reliable version is the assumption that swords carved on monoliths mean either the number of people buried in this place, or the number of deaths at the hands of a warrior who found his last refuge here. While the mysterious monoliths of Tiya hold their secrets sacredly, it is hoped that further research will answer the questions of who, why and when they built these steles.
