Mtskheta, Georgia's ancient capital and a UNESCO World Heritage Site, served as the political and religious center of the kingdom from the 3rd century BCE until the 6th century CE. It is renowned for its early Christian heritage, including the 4th-century Svetitskhoveli Cathedral, a masterpiece of medieval architecture housing sacred relics. The site also features the 11th-century Samtavro Monastery and Jvari Monastery atop a hill, overlooking the confluence of the Mtkvari and Aragvi rivers. Together, these monuments exemplify Georgia's pivotal role in the spread of Christianity in the Caucasus.
