The port of Siracusa, known as Porto Grande, is situated on the SE coast of Sicily and to the W of Baia di Siracusa. The city of Siracusa lies primarily on the mainland at the N end of the harbour, but overspills SE onto Isola Ortigia. There are two defined anchorages, A and B, within the harbour. Holding in mud in the N anchorage, B, is poor; that in A is better.
