Sos (hy|Սոս) is a village in the Khojavend District of Azerbaijan, in the disputed region of Nagorno-Karabakh. Until 2023 it was controlled by the breakaway Republic of Artsakh. The village had an ethnic Armenian-majority population[2] until the exodus of the Armenian population of Nagorno-Karabakh following the 2023 Azerbaijani offensive in Nagorno-Karabakh.[3]
During the Soviet period, the village was a part of the Martuni District of the Nagorno-Karabakh Autonomous Oblast.
Historical heritage sites in and around the village include Amaras Monastery (established in the 4th century, rebuilt in 1858), the 5th/6th-century St. Lusavorich monastic complex and pilgrimage site, the 19th-century St. George's Church (hy|Սուրբ Գևորգ եկեղեցի|Surb Gevorg Yekeghetsi), and the Tevosants spring monument (1902).[1] [4]
The population is mainly engaged in agriculture and animal husbandry. As of 2015, the village has a municipal building, a house of culture, a secondary school, a kindergarten, three shops, and a medical centre.[1]
The village had 1,016 inhabitants in 2005,[5] and 1,089 inhabitants in 2015.[1]
