History
The former seal of Oni devised during the Imperial Russian rule.
The territory of modern-day Oni has been inhabited since the Bronze Age. Archaeology revealed the artifacts of Colchian culture, particularly a collection of Colchian coins dating back to the 6th–3rd centuries BC. Oni is first chronicled in the 15th century, though a legend has it that the town was founded by the 2nd BC king Pharnajom of Iberia. Located on the crossroads from Northern Caucasus, Kartli (central Georgia), Imereti (western Georgia) and Lower Rach’a, Oni developed into a typical late medieval commercial town and was contested between the kings of Imereti and the princes of Rach’a. The town was absorbed by Imperial Russia in 1810, and made it, in 1846 the administrative center of the Racha Uyezd of the Kutaisi Governorate. During the Soviet Union, the town was united with a number of surrounding villages into the Oni district, which is currently administered as a part of the Racha-Lechkhumi and Lower Svaneti region.
In recent decades Oni has suffered from earthquakes and a series of avalanches. A particularly severe earthquake occurred on 29 April 1991. The earthquake measured 7.0 on the moment magnitude scale with a maximum MSK intensity of IX (Destructive), the most powerful ever recorded in the Caucasus Mountains, and caused significant damage to the infrastructure of Oni.
Despite a post-Soviet tendency towards migration, Oni still retains a small number of Jewish families – remnants of once powerful and large historic Jewish community, Georgia's third largest, after those of Tbilisi and Kutaisi. The Oni Synagogue was built in the 1880s by a Polish architect and the builders were Greek Jews from Thessaloniki.[2]
Oni and its environs house a number of historical monuments, including the ruins of medieval forts and Georgian Orthodox churches. A popular spa, Shovi, and Utsera are located some 15 to 30 kilometres (9 to 19 miles) from Oni, on the southern slopes of the Greater Caucasus mountains. The Racha Regional Museum, located in Oni, has an impressive collection of 14000 unique artifacts from the fields of archaeology, ethnography, numismatics, natural history, fine art, historical documents, manuscripts, and printed books.
There was a large community of Georgian Jews which explain the presence of the Oni Synagogue but they emigrated to Israel after the fall of USSR and only a few remain to look after synagogue.
