Zadar is a city in Croatia on the Adriatic Sea. It is the centre of Zadar county and the wider northern Dalmatian region. Zadar faces the islands of Ugljan and Pašman, from which it is separated by the narrow Zadar Strait. The promontory on which the old city stands used to be separated from the mainland by a deep moat which has since become a landfill. The harbor, to the north-east of the town, is safe and spacious. Zadar is the seat of a Catholic archbishop.
Zadar gained its urban structure in Roman times; during the time of Julius Caesar and Emperor Augustus, the town was fortified and the city walls with towers and gates were built. On the western side of the town were the forum, the basilica and the temple, while outside the town were the amphitheatre and cemeteries. The aqueduct which supplied the town with water is partially preserved. Inside the ancient town, a medieval town had developed with a series of churches and monasteries being built.
Major industries include tourism, traffic, seaborne trade, agriculture, fishing and fish farming activities, metal manufacturing and mechanical engineering industry, chemicals and non-metal industry and banking.
