Two km southeast of Aghaiani rises Mount Tkhoti, dividing the Mtkvari valley from the Mukhrani plain, its eastern slopes descending toward the Ksani. Mount Tkhoti is linked with the story of the first Christian king, Mirian, and the eclipse of the sun. After that miracle, in the very first centuries after the adoption of Christianity, a chapel in the name of St. Nino was raised on the summit of Tkhoti. The Ninotsminda church now standing on Mount Tkhoti dates to the 7th–8th centuries. In its original form it was a cross-domed church, remodeled as a hall church at the turn of the 9th–10th centuries. Fragments of painting and an inscription survive in the sanctuary; the conch bears Christ Enthroned. The painting dates to the 10th–11th centuries. On the south facade is a three-line Asomtavruli inscription of the 10th–11th centuries.
