The catastrophic floods in the Libyan city of Derna that killed thousands of people damaged the archaeological site of the ancient Greek city of Kyrenia. However, these floods brought to light new archaeological finds.

In its ruins Cyrenewhich the locals call Sehat and has been attracting travelers since the 18th century, an unearthed to date unknown Roman drainage system.

“The floods have brought to light a new site – a water channel which I believe dates back to the Roman period. It is a special discovery for the city,” said local antiquities department official Adel Boufzra.

Cyrene was a Greek colony and one of the main cities of the ancient Greek world before it became an important center under the Romans until an earthquake destroyed the city in the year 365.

The ancient Greek city is one of Libya’s five UNESCO World Heritage Sitesalong with the extensive ruins of the Roman period at Sambratha and Leptis Magna.

The Libyan official warns that – although the damage so far is minor – the floods may have exacerbated land subsidence that could later topple one of the monuments.

“I’m almost certain, and I expect, that one of these attractions could collapse during the winter due to too much groundwater,” he said.
