Farthest View of the Eiffel Tower: Possibly from Mont Blanc's Summit

Claims vary, but many sources cite the summit of Mont Blanc (4,808 m) as the farthest point from which the Eiffel Tower can be seen—approximately 250–300 km away under exceptional atmospheric conditions.

Factors Affecting Visibility

• Curvature of the Earth
• Atmospheric refraction
• Weather, pollution, time of day
• Observer elevation

While theoretical line-of-sight allows it, actual sightings are rare and require perfect clarity.
