Figures and Churches Relief. For centuries the royal capital was Mtskheta, where the Aragvi meets the Mtkvari — today a UNESCO-listed town and the spiritual heart of the country. A relief with churches and buildings, carved into the bronze of a pillar. Some of the oldest dated Georgian inscriptions, from the 5th century, are carved in the Bolnisi Sioni church — stone, like these pillars, chosen to make words last.
