This cross-domed church of St. Eustathius (Estate), from the first half of the 13th century, stands in the center of the village of Ertatsminda, Kaspi municipality. A large carved cross adorns each of its four sides. Stylistically it echoes the 12th–13th-century monuments of Ikorta, Pitareti, Betania, Kvatakhevi, Tsughrughasheni and others.
