Greece's Acropolis closed from 11:00-15:00 BST due to a heatwave with temperatures reaching 42°C (107°F). This is not the first time extreme heat has forced the closure of the ancient site. A mandatory five-hour work stoppage for outdoor workers is also in place. Wildfires are raging across Greece, Catalonia, and France, adding to the extreme weather conditions. The heatwave is expected to continue into Wednesday before easing on Thursday. Authorities urge vigilance.
