In other words, 0.50 kilometers is 2.20 times the height of The Golden Gate Bridge, and the height of The Golden Gate Bridge is 0.4550 times that amount.(San Francisco, California and Marin County, California) (height above water)
The height of each tower of Golden Gate Bridge is 0.2270 kilometers 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 two-and-a-half times as tall as The Space Needle.
In other words, 0.50 kilometers is 2.720 times the height of The Space Needle, and the height of The Space Needle is 0.3680 times that amount.(Seattle, Washington) (to aircraft warning beacon at peak)
Built for a 1962 World's Fair, the Space Needle stands 0.1840 kilometers 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 three times as tall as St. Paul's Cathedral.
In other words, 0.50 kilometers is 2.870 times the height of St. Paul's Cathedral, and the height of St. Paul's Cathedral is 0.3480 times that amount.(London, England, United Kingdom)

In other words, 0.50 kilometers is 2.95350 times the height of The Washington Monument, and the height of The Washington Monument is 0.338580 times that amount.(Washington, D.C.)
The Washington Monument measures 0.169290 kilometers 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.
