Santorini Caldera: Building licenses suspended (MAP)

Greece’s Environment Ministry suspends building licenses in the wider zone of the caldera on the islands of Santorini and Therasia to protect them from landslides. The Ministry included a relevant clause in draft legislation published for public consultation on Thursday.
