Some background about Colentum!

The island of Murter was inhabited in prehistoric times by the Illyrians.

Colentum was founded by the Liburnians in the 11th century BC. It was transformed into a Roman town in the 1st century BC. The town had a typical antique architecture of multi-story houses, water cisterns, baths and narrow streets paved in stone slabs.

The area is known to include sections of both the Liburnian and Roman towns, an acropolis and a necropolis. All of which are open to the public to explore and scavenge.

What Happened to Colentum?

Based on recent archaeological research and the discoveries of mosaics and frescoes, it is believed that Colentum was a rich town. There are many theories about the town’s demise. One is that pillaging pirates raided the town one time too often, causing the locals to abandon the site. Another is that an earthquake destroyed the town. However, the passage of time and human activities have added to the areas destruction. It is believed that the upper part of Colentum was destroyed more than once by torrential rain and flooding and the lower parts were flooded by the sea as sediment washed down from the hills.

The archaeologist Veljko Paskvalin wrote that local legend states that the Greeks took away the treasures long ago and the local pillaging of stone for the building of the Church of the Lady of Gradina added to the demise in 1774.
