Around a thousand people were evacuated from the Eiffel Tower on Christmas Eve after a fire alarm.
The alarm was set off by a short circuit in the elevator system between the second floor and the top of the tower, the management company said in a statement. There was no fire.
“It turned out to be a short circuit in an elevator power rail,” said a spokesperson for SETE, the tower's management company.
“The technical problem occurred between the second floor and the top of the monument, causing the fire alarm to be triggered at 10.50am.
“In accordance with current safety procedures, we evacuated the monument.”
The spokesman added that there was no fire, and no visitors were put in danger.
Investigations were then carried out to "identify the origin of this incident". The tower reopened gradually later on Tuesday.
The incident happened not long after the nearly £1 billion restoration of Paris' Notre Dame Cathedral was unveiled.
The iconic building was severely damaged in a blaze in 2019. That incident caused fire security drills to be stepped up at other French landmarks.
The tower is one of the most recognisable tourist sites in the world and is visited by around six million people a year.
