The Eiffel Tower will be protected by a bulletproof glass wall in a bid to prevent terrorist acts at the landmark in Paris.
The 2.5 metres high walls will cost €20million, and be built at the northern and southern ends of the monument, with the deputy mayor Jean-Francois Martins telling a news conference in Paris (via the BBC): "The terror threat remains high in Paris and the most vulnerable sites, led by the Eiffel Tower, must be the object of special security measures.
"We will replace the metal grids to the north and south with glass panels which will allow Parisians and visitors a very pleasant view of the monument.
"We have three aims - to improve the look, make access easier and strengthen the protection of visitors and staff."
The glass walls are meant to be preventative measure against individuals or vehicles storming the site, which attracts more than six million visitors a year.
"Inelegant temporary" barriers which were erected on the western and eastern sides during the Euro 2016 football tournament will be replaced by ornate fences, Martins also announced.
Removing the barriers would give tourists "a nicer view of the monument", and architects will be commissioned to design the walls to blend in with the river, he added.
Last year, 86 people were killed when a lorry ploughed into pedestrians celebrating Bastille Day in the southern city of Nice.
Earlier this month, a man wielding machetes attacked troops patrolling outside the Louvre Museum in Paris, with President Francois Hollande saying there was little doubt it was a terrorist attack.
