The flag on the Eiffel Tower is the French flag, also known as the tricolore. In fact, there are usually two French flags displayed.
The French flag is a three-banded (tricolour) flag featuring three vertical bands coloured blue (hoist side), white, and red. These colours represent:
- Blue: Represents liberty.
- White: Represents equality.
- Red: Represents fraternity.
These values are central to the French Republic and are often invoked alongside the flag. The flags are typically flown at the top of the tower and are visible from across Paris.
