UNESCO Endangered Status Brief

Primary Threat: Over-Tourism Infrastructure Stress & Cliff Erosion

With up to 18,000 cruise passengers disembarking daily onto an island of 15,000 residents, water desalination plants and waste disposal are beyond critical thresholds, accelerating soil destabilization.

The Sanctuary & Its Fragile Ground

Carved deep into the volcanic cliff face centuries ago by local fishermen needing thermal shelter from summer Meltemi winds, this cave suite stays naturally cool without air conditioning. Away from the selfie stick corridors, enjoy a quiet terrace overlooking the submerged ancient caldera rim, illuminated by the soft twilight of the Aegean.
