Tbilisi, the capital of Georgia, on the intersection between Europe and Asia, nestled between the Black Sea and the Caspian Sea. A onetime Silk Road capital, this sprawling city is as eclectic as it is dynamic. The medieval cobbled streets of the Old Town with its traditional pastel houses, wooden balconies and ancient hot spring baths flow seamlessly into hyper-modern structures and the Art Nouveau neighborhood of Sololaki.
