Athens – In June 2024, the heat in the Greek capital Athens was unbearable. Temperatures well over 40 degrees Celsius during the day and nights in which the thermometer did not drop below 30 degrees made life difficult for people. It was the hottest June on record. A special measure is intended to provide relief in the future: the reactivation of the 2,000-year-old, 23-kilometer-long Roman Hadrian Aqueduct.
