The Eiffel Tower in Paris is being evacuated after a man was seen climbing up the side of the structure on Monday afternoon, officials told CNN.
Visitors began tweeting pictures and videos of the individual climbing up the tower, which is 1,062 feet tall.
“The Eiffel Tower has been closed and is in the process of being evacuated because a person is scaling it,” a spokeswoman for the landmark said.
Firefighters are at the scene and have established contact with the man climbing the tower, a spokesman for the fire brigade said.
Irish tourist Claire Murphy, who is on vacation in Paris, told CNN that the lockdown began at 2:15 p.m. local time and that she was still stuck on the tower’s top floor.
Almost seven million people visit the Eiffel Tower every year. Completed in 1889, it was designed and built by Gustave Eiffel as part of a “Universal Exposition” marking the centenary of the French Revolution. It celebrated its 130th anniversary last week.
In 2017, a protective glass wall, 65 millimeters thick and resistant to bullets, was erected around the base of the tower to provide increased security.
