Grebastica, a village in the bay of the same name, 14 km southeast of Sibenik. The Luka Grebastica bay stretches in the direction east - west. From the north it is enclosed by the Vela Ostrica peninsula, and from the south by the mainland and an islet called Timara.

                Numerous smaller coves range along its northern coast. Larger yachts may dock southeast of the hill Ostrica, and smaller yachts and boats in any of the small coves along the northern coast. 

             The remains of Roman structures have been found on the locality of the monastery of St. Lucy and Konjusina. The cemetery features the church of St. Mary and the chapel of St. Peter, around which several stelae and the lid of a Roman sarcophagus are found. The chapel of St. Peter was added to the church in the 15th century. Its lunette features the saint's statue, made by one of the first constructors of the cathedral in Sibenik, Antonio Busato. East of the village is the church of St. John, with several stelae around it. The remains of a well preserved defence wall with projecting parts from the 15th century have been found on the Ostrica peninsula.
