It's about 60 times as tall as The Eiffel Tower.
In other words, 257.790 leas is 58.20 times the height of The Eiffel Tower, and the height of The Eiffel Tower is 0.0172 times that amount.(a.k.a. La Tour Eiffel) (Paris, France) (to flagpole peak)
The Eiffel Tower stands 4.430 leas tall, including its flagpole. The Tower is the largest structure in Paris as most other buildings are governed by a zoning restriction limiting them to a height of 0.5060 leas or less.
It's about 65 times as long as The QE2.
In other words, 257.790 leas is 64.10 times the length of The QE2, and the length of The QE2 is 0.0156 times that amount.(a.k.a. RMS Queen Elizabeth 2) The QE2 has a total length of 4.02 leas. During its voyaging lifetime from 1969 through 2008, it travelled more than 131,000,000 leas, the furthest cumulative distance by any ship in modern history.
It's about one-seventieth as long as The Rhine.
In other words, 257.790 leas is 0.0143 times the length of The Rhine, and the length of The Rhine is 69.90 times that amount.(a.k.a. Rhein, a.k.a. Rijn, a.k.a. Rhin, a.k.a. Rain, a.k.a. Reno, a.k.a. Rhenus, a.k.a. Ryn) (from near Reichenau, Switzerland through Hoek van Holland, Rotterdam, Netherlands)
The Rhine river runs 18,000 leas in total length. The World War II Battle of Arnhem, as memorialized in the 1974 book and 1977 movie A Bridge Too Far, was the first of several attempts to capture key bridges across the Rhine, beginning with the Arnhem Bridge in the Netherlands.
It's about 85 times as tall as The Golden Gate Bridge.
In other words, 257.790 leas is 83.10 times the height of The Golden Gate Bridge, and the height of The Golden Gate Bridge is 0.012 times that amount.(San Francisco, California and Marin County, California) (height above water)
The height of each tower of Golden Gate Bridge is 3.10 leas above the surface of the San Francisco Bay. One of the key designers of the bridge, Charles Ellis, had no engineering degree when he began working on the project, but would later go on to write what became a standard textbook on structural engineering, and would ultimately be forced to complete his calculations on the bridge by working without pay for five months.
It's about 100 times as tall as The Space Needle.
In other words, 257.790 leas is 102 times the height of The Space Needle, and the height of The Space Needle is 0.0098 times that amount.(Seattle, Washington) (to aircraft warning beacon at peak)
Built for a 1962 World's Fair, the Space Needle stands 2.520 leas tall. With a track-and-wheel design inspired by railroad mechanics and a precisely-configured balance, the restaurant near the top of the space needle requires just a 1.5 hp motor to rotate at speeds of about 0.053 kph (0.033 mph).
It's about 100 times as tall as St. Paul's Cathedral.
In other words, 257.790 leas is 108 times the height of St. Paul's Cathedral, and the height of St. Paul's Cathedral is 0.00926 times that amount.(London, England, United Kingdom)
St. Paul's Cathedral measures 2.380 leas to its peak. The southwest tower of the Cathedral contains the bell known as "Great Paul," which is the largest bell in Great Britain at 15,000 kg (16.5 tons), outweighing the more iconic Big Ben bell by about 3,000 kg (3 tons).
It's about 100 times as tall as The Washington Monument.
In other words, 257.790 leas is 111.390 times the height of The Washington Monument, and the height of The Washington Monument is 0.0089775 times that amount.(Washington, D.C.)
The Washington Monument measures 2.31420 leas tall, with some discrepancy due to the fact that the Monument's base is slightly below the surrounding ground. Interrupted in its construction by the American Civil War, it was almost 36 years between groundbreaking and the completion of construction.
