Church of St. Spasa - ruins of an old Croatian church built in the 9th century. It is located in the village of Cetina, at the source of the river of the same name, 8 km from Vrlica. The village was named after the river Cetina and the old Croatian parish Cetina, which was first mentioned in the 10th century by the Byzantine emperor Constantine VII. Porphyrogenet. This old Croatian church was built in the last quarter of the 9th century during the reign of Branimir, the Croatian prince of Primorska Croatia. The church was built by Gastika (Gostiha), the prefect of Cetinje, in memory of his mother and his sons, as recorded on the found fragments of the altar fence.
