Greece is a popular tourist destination for Britons, with many visitors flocking to the country’s beautiful islands, known for their stunning beaches and azure waters. The country’s history is also a major draw for visitors, with millions of tourists flocking to the Greek capital of Athens to see its famous landmarks, including the Acropolis.

But holidaymakers have been warned that tourism is “under threat” from “successive heatwaves”. The country has already suffered scorching heatwaves this summer, with attractions including the Acropolis temporarily closed to visitors in June.
