"At the request of Mayor of Paris, Anne Hidalgo, the Eiffel Tower will be symbolically dark this evening, Wednesday 14 December, to demonstrate the support of Paris to the besieged inhabitants of the city of Aleppo in Syria," the tower's management announced on its website.
"This symbolic measure, on a monument observed throughout the world, aims to challenge the international community on the urgency to act," the statement continued.
Aleppo was once Syria's most populous city but has withered under a brutal five-year civil war.
Since July, hundreds of civilians have been killed and thousands remained trapped in rebel-held neighborhoods of east Aleppo that have been encircled by Syrian government forces and subjected to intense shelling and aerial bombardments.
The tower's official Twitter account posted a photo with the announcement earlier in the day.
