This photograph shows an ancient well, part of Hadrian's Aqueduct, on the grounds of the Athens Olympic Sports Complex in Athens on January 27, 2025. Between parked cars in a suburban street in Athens, workers fix a pump to an ancient stone well that in turn accesses an aqueduct built almost 2,000 years ago, hailed by experts as an "engineering marvel" as the Greek capital, one of Europe's hottest and most densely populated cities, is going to great lengths -- and depths -- to battle soaring summer temperatures and creaking infrastructure.
