Ambrolauri in the context of "Ossetian Military Road"

Racha (also Račha, Georgian: რაჭა [ˈɾät͡ʃ'ä], Račʼa) is a highland area in western Georgia, located in the upper Rioni river valley and hemmed in by the Greater Caucasus mountains. Under Georgia's current subdivision, Racha is included in the Racha-Lechkhumi and Kvemo Svaneti region (mkhare) as the municipalities of Oni and Ambrolauri. Native inhabitants of Racha are called Rachians, an ethnographic group of Georgians.

Racha occupies 2,854 km in the north-eastern corner of western Georgia. Spurs of the Greater Caucasus crest separates Racha from the Georgian historical regions of Svaneti and Lechkhumi on the north-west and from Imereti on the south, while the main Caucasus ridge forms a boundary with Russia’s North Ossetia. On the east, Racha is bordered by breakaway South Ossetia, officially part of Georgia's Shida Kartli region.

Racha-Lechkhumi and Kvemo Svaneti (Georgian: რაჭა-ლეჩხუმი და ქვემო სვანეთი, Rach’a-Lechkhumi da Kvemo Svaneti [ɾät͡ʃʼäle̞t͡ʃʰχumi d̥ä kʰʷe̞mo̞ s̪ʷän̪e̞t̪ʰi]) is a region (mkhare) in northwestern Georgia with a population of 28,500 (2021), making it the most sparsely populated region in the country. It has a nominal area of 4,954 km (1,913 sq mi), of which 4,600 km (1,800 sq mi) is de facto controlled by Georgia. The remainder is effectively under South Ossetian control. The region has Ambrolauri as its administrative center and Parmen Margvelidze is governor of the region since June 2021. Racha-Lechkhumi and Kvemo Svaneti includes the historical provinces of Racha, Lechkhumi and Kvemo Svaneti (or Lower Svaneti).
