More info: Zirje has remnants of a late-Hellenic fort erected in the 6th century as well as traces of other ancient defensive structures around the island. The island first belonged to Zadar and then became part of Sibenik in 1323. When the 15th and 16th-century Venetians controlled the Dalmatian coast Sibenik's aristocratic families built summer houses on Zirje. Later the economy, based on fishing and farming, foundered and much of the population emigrated.
Standing atop a hill and with views of the entire island, are the ruins of the fortress of Zirje, built in the sixth century by the Byzantine emperor Justinian I. It was originally 100mtrs high and had five towers.
The ferry port on the island provides a link to city of Sibenik. From port to port, the route is currently served by two companies at different times throughout the day.
