Grotto of Saint Onuphrius, Ulashkivtsi

By the 15th century CE, the site evolved into a Christian skete, marking the beginning of Christian monasticism in the region. The grotto and its surroundings have revealed artifacts from various periods, including the Late Paleolithic-Mesolithic era, and cultures such as the Trypillian, Komarivska, and Goligradska.
