Dodos Rka (Dodo's Horn) is a monastery and former feudal seigneury of old Georgia, an important monument of Georgian architecture within the David Gareji monastery complex. It was founded in the first half of the 6th century by Dodo, one of the disciples of David of Gareji. According to Georgian hagiographic sources, Dodo was David's closest disciple and co-worker, a native of Kakheti of the Andronikashvili family, who joined the Gareji fathers after taking monastic vows.
