With around 93,000 inhabitants, it is the third-largest city in Thuringia after Erfurt and Jena as well as the easternmost city of the Thüringer Städtekette, an almost straight string of cities consisting of the six largest Thuringian cities from Eisenach in the west, via Gotha, Erfurt, Weimar and Jena to Gera in the east. Gera is the largest city in the Vogtland, and one of its historical capitals along with Plauen, Greiz and Weida. The city lies in the East Thuringian Hill Country, in the wide valley of the White Elster, between Greiz (upstream) and Leipzig (downstream).
