The architectural complex of Ninotsminda is surrounded by a fortification with angular towers and a crenellated curtain wall dating back to the 16th century. The fortified entrance door has projecting towers with beehive-shaped machicolations. The original cathedral, was collapsed in the 19th century. Only the apse and a portion of the western wall remain today. The contours of the foundations indicate that the church originally had an octagonal centre, surrounded by corner niches. The large brick bell tower dates back to the reign of King Levan of Kakheti (1520-1574). The three lower floors served as residences and each floor had a chimney. The staggered arrangement of bricks on the exterior façade to form geometric patterns and the pointed arch above the entrance indicate the cultural influence of Persia.
