Life on the peninsula is safer if you build a wall from one side to another.
Near the settlement of Grebaštica on the Oštrica peninsula, there is a wall that separates the peninsula from the rest of the world. It was built at the end of the 15th century as part of the defense fortification system of the city of Šibenik for defense against the Turks. It is between 6 and 9 meters high and 60 to 80 cm wide.
After the end of the Turkish threat, a separate part of the peninsula served as a quarantine for plague victims. Today, Oštrica beach is a little-known paradise. Additional attractiveness to this area is given by herds of mouflon, wild sheep with characteristically curved horns.
