In the middle of the 6th century, one of the Assyrian fathers Abibos arrived in Kakheti to preach Christianity. He became the bishop of Kakheti and the monastery of Nekresi became his residence, later he was executed by the Persians. In addition to teaching about Christ, the monastery was an important scientific and educational center. Nekresi complex comprises several monuments of Georgian architecture. The small basilica of the second half of IV century is one of the first churches in Georgia, built in Nekresi during the rule of King Mirian, the first Christian king. The building also includes an ancient wine cellar - Marani, where monks made wine in traditional clay jugs, called Kvevris.
