Ever since the stone obelisk was completed in 1884, however, the historic height has been recorded at 555 feet, 5 and 1/8 inches. It's a number circulated for decades on tours of the capital and in civics classes about the monument honoring the nation's first president.

At this time the answer remains unclear, but what is certain is that the current estimate of the height can now be definitively stated to be +/- 1/32 inches. It only took more than a century, but we now know how tall the Washington Monument really stands thanks to—you guessed it—science. Oh, and we know the exact location, too. Finally.

Earlier survey results showed the monument did not sink any further into the ground as a result of the 5.8-magnitude earthquake. The monument was built on land that used to be underwater, and it has sunk about 2.2 inches since 1901. Lest anyone be confused by the changing measurements, the National Park Service as caretaker of the monument has no intention of changing its brochures or description of the height to reflect the new numbers.

Well, in this case, it's important for measuring how much the monument is changing. We've covered the long saga of how the monument was damaged in an earthquake that struck D.C. in 2011, precipitating a long restoration to fix more than 150 cracks in the structure that only just wrapped up.

When the monument was completed in 1884, it was the world's tallest structure until 1889 when the Eiffel Tower was built. It remains by far the tallest structure in the nation's capital, which strictly restricts building heights. Most buildings are shorter than the U.S. Capitol dome, which rises 288 feet.The new survey was conducted while the monument was wrapped in scaffolding for restoration work following a 2011 earthquake.

Finally. Odd though it sounds, it's actually not surprising. The Washington Monument was built in 1848, long before the technical standards for building height we use today were established (much less the technology to find them).
