The Eiffel Tower was evacuated on Wednesday after French police received a bomb threat.
The evacuation of the Paris monument took place at around midday local time (11am BST), but reopened two hours later.
A police spokesperson told The Independent that officers were dispatched to the scene to investigate.
Several roads around the Eiffel Tower were also closed off to traffic.
“The tower was evacuated just after midday following instructions from the police,” a spokesperson for the Eiffel Tower said.
“It took around an hour to evacuate everybody. Police are at the scene and we don’t have any other information at this stage."
Security measures at the landmark were strengthened in 2018 to protect against potential terror attacks.
The base of the tower was enclosed with bullet proof glass and additional security checks were introduced for visitors.
Between March and June the Eiffel Tower was closed to the public as a result of the coronavirus pandemic.
