As a heat wave scorches most of Europe, the Eiffel Tower announced it will be closing early on Tuesday as Paris is expected to hit triple-digit temperatures.

Europe’s heat wave is set to peak over the coming days, with a blast of Saharan air triggering red alerts from France to the Swiss Alps.

Barcelona recorded its hottest June in over a century, the summit of Paris’ iconic Eiffel Tower was closed to visitors and hundreds of French schools shut on Tuesday as Europe sizzled in its first major heat wave of the summer.
