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.
