In the Middle Ages, Kartli was traditionally divided, roughly along the Mtkvari river into the three principal regions: Shida Kartli (Inner Kartli), Kvemo Kartli (Lower kartli) and Zemo Kartli (Upper Kartli). The historical lands of Kartli are currently divided among several administrative regions of Georgia and All these regions have their regional capitals: Gori (Shida Kartli), Rustavi (Kvemo Kartli), Akhaltsikhe (Samtskhe-Javakheti) and Mtskheta (Mtskheta-Mtianeti). The population of Kvemo Kartli is mixed between Georgians,Azerbaijanis, Armenians, Russians, Caucasus Greeks and others. There are many antique memorials there, including the oldest extant Bolnisi church built in 480 and the Georgian Orthodox Church Betania-the great masterpiece of “Golden Age” architecture of Georgia. The most favorite destinations for visitors of Kvemo Kartli is Dmanisi Archaeological site, where the skulls of first Europeans were discovered and Birtvisi Canyons, where the natural labyrinth of massive complex of capstones attracts amateurs of climbing and hiking.
