Plaza with Pillar Gateways. The pillars are joined at the top by heavy arched lintels, so walking between them feels like passing through the gates of a stone book. A 360° view from the upper plaza, where the giant pillars stand in a ring on the summit of the hill. Queen Ketevan the Martyr, who refused to abandon her faith in Persian captivity in 1624, is honoured by the Georgian Church as a saint.
