Set on the foothills of the Gombori Mountains and the Great Caucasus, Telavi is the main city and administrative center of Georgia's eastern Kakheti province. Rising in the vineyard-covered Alazani Valley at nearly 500 meters above sea level, its historic fortress and the Castle of Batoni crown a landscape prized for its fresh mountain air. Batonis Tsikhe, the residence of the kings of Kakheti, retains its walls and towers, a royal palace, a bathhouse, and two court churches within a single enclosure, and is associated above all with Erekle II, who ruled from here in the eighteenth century. The town serves as the working capital of Georgia's best-known wine region, and an ancient plane tree stands at its center.
