Can you see the Eiffel Tower from London (The Shard viewing gallery)?

No, Earth is in the way

340 km line of sight toward the south-southeast (bearing 149°), computed on 30 m Copernicus terrain with Earth curvature and standard atmospheric refraction.

The answer

No. The Eiffel Tower is 340 km from London and sits about 6,904 m below the horizon at standard refraction: Earth's curvature hides it.

From 244 metres up, London's tallest viewing gallery looks south over the Channel on a clear day. Paris is 341 kilometres away, and the question comes up every time someone reaches the top with good visibility.

No terrain trickery needed here: the planet itself is the obstacle. Over 340 km, Earth's curvature drops the Eiffel Tower a full 7,880 m below a flat sightline, leaving its summit about 6,904 m under the grazing line from London (The Shard viewing gallery). No viewpoint at this location, however clear the day, can see over that.

The two towers are among the tallest structures in their countries and it makes no difference at this range. To see the Eiffel Tower's tip from the Shard, one of them would have to be several kilometres tall. What people do see from the Shard on the clearest days is the French coast near Calais, 150 kilometres out, which is a real and much shorter sightline.

The terrain profile

Elevation profile from London (The Shard viewing gallery) to the Eiffel Tower. Like every elevation profile, the vertical axis is stretched (≈15× here), but the geometry is real: mid-path, Earth's surface genuinely stands 2,267 m above the straight line between the two points (the dashed arc is sea level). Light bends only slightly around that bulge, so whatever it covers stays hidden. Each ray runs solid until terrain cuts it, then continues as the faint ghost of the sightline you would need. Even the stronger-bending ray of a thermal inversion (k = 0.17) stays cut off.

Frequently asked questions

Can you see the Eiffel Tower from London (The Shard viewing gallery)?

No, not under standard atmospheric conditions. Across 340 km, the view is cut off before reaching the target (see the terrain profile above for exactly where).

How far is the Eiffel Tower from London (The Shard viewing gallery) in a straight line?

340 km great-circle distance, on a bearing of 149° (south-southeast).

What exactly blocks the view?

Earth's curvature. Over this distance the target drops about 7,880 m below a flat sightline and ends up roughly 6,904 m below the horizon. Only exceptional atmospheric refraction can (sometimes) lift it into view.

How was this calculated?

UpToWhere walks the full terrain profile between the two points on 30 m-resolution Copernicus GLO-30 elevation data, applying Earth curvature and standard atmospheric refraction (k = 0.13), the same physics surveyors use. You can run the same point-to-point check between any two places on Earth.
