The iconic tower -- like monuments the world over following the deadly jihadist attacks on Paris -- will be lit up in the French national colours blue, red and white from sundown, its operator said today.
Normally visited by between 15,000 and 20,000 people a day, the tower was closed until further notice after Friday's attacks.
But it has now reopened, and will glow with the patriotic colours for the next three evenings, the company said.
The illumination will also include the defiant Latin slogan of Paris, "Fluctuat nec mergitur" meaning "It is buffeted by the waves, yet remains afloat."
The illumination resumed yesterday, but without the light show, during which the tower erupts in bursts of lights, appearing to dance and float in the night.
The Sydney Opera House and One World Trade Center in New York have been among structures around the world to light up in blue, white and red in solidarity with France.
