Remains say: Nin as far back as the 9th century BC was a strong maritime and trading centre and an important port on the eastern coast of the Adriatic. It was founded by the Illyrian tribe of Liburnians, under the name of Aenona which had an important trading role. The ancient port of old Nin is one of the largest and according to findings the richest port area from that period on the eastern Adriatic. During low tide on the headland called Kremenjača near the tourist settlement of Zaton Holiday Resort the remains of the breakwater and ancient walls from the 1st century BC can be seen.
