Amathous Harbour was constructed during the Hellenistic period by Demetrios Polirketes. It consisted of two parts, the outer and the inner port. The outer port measured around 100 metres by 180 metres and was delineated by wharves in the east and a breakwater in the south. Access was through an opening on the east wharf. The port had a short life as it soon silted up and the sea level dropped.
By the 3rd century B.C. the harbour was used only by fishermen and by the 1st century A.D. was completely dry. Today it lies below sea level, but is easy to distinguish.
The inner port stood behind the outer port and was where mariners moored their ships in order to protect them from bad weather. It was abandoned quite early because of the silting up of the outer port.
