You’ve seen it a thousand times — on the news, in movies, maybe in person, that simple white needle pointing at the sky over the National Mall. But the most photographed obelisk in America is hiding some genuinely strange stories. It was once the tallest thing humans had ever built. It’s capped with a metal that used to be more precious than silver. And if you look closely, you can literally see the spot where the country gave up on it for two decades. Number 4 is sitting right at the top, and almost nobody on the ground has ever read it.
1. It was the tallest building in the world when it was finished.
When the Washington Monument was completed in 1884, its roughly 555 feet made it the tallest structure on Earth — taller than any cathedral, pyramid, or skyscraper that had ever existed. It held the world record for only about five years. In 1889, a certain iron tower went up in Paris and stole the crown. The Eiffel Tower knocked America’s monument out of first place, and it never got the title back. For a brief, glorious moment, though, the tallest thing humanity had ever built was a tribute to George Washington.
2. You can see exactly where they ran out of money.
Look at the monument on a clear day and you’ll notice the marble changes color about a third of the way up. That’s not a trick of the light — it’s a scar. Construction started in 1848 but ground to a halt in the 1850s thanks to a funding crisis, political infighting, and then the Civil War. Work didn’t resume in earnest until the 1870s. By then the original quarry’s marble was unavailable, so the builders used stone from different sources that has weathered differently over time. The result is a permanent two-tone stripe — a visible monument to roughly two decades of American dysfunction.
3. It’s completely hollow inside.
For all its mass, the Washington Monument is not a solid block of stone. It’s a hollow Egyptian-style obelisk, with walls that are about 15 feet thick at the base and taper to just 18 inches near the top. The empty shaft running up the middle is what makes room for the elevator and the 897 steps that wind up to the observation level. The ancient Egyptians built obelisks to honor their leaders thousands of years ago — and 19th-century America borrowed the exact same form to honor its first president.
4. It’s capped with a chunk of aluminum — back when aluminum was a luxury metal.
The very tip of the monument is a small pyramid of cast aluminum, about nine inches tall. Today aluminum is so cheap we wrap leftovers in it, but in 1884 it was a rare and dazzling novelty — pound for pound, it cost about as much as silver. The cap was the largest single piece of aluminum ever cast at the time, chosen because it wouldn’t tarnish and could double as part of a lightning-protection system. Before it was hoisted to the top, it was reportedly put on display at Tiffany’s in New York, where people could step over it and brag they’d walked over the apex of the Washington Monument.
5. There’s a message to God at the very top that no visitor can read.
Engraved on the east face of that aluminum apex are two Latin words: “Laus Deo” — meaning “Praise be to God.” It’s positioned to catch the first light of the rising sun each morning. The other three faces of the cap carry names and dates from the monument’s construction, but that single phrase sits hundreds of feet above the heads of everyone below, completely invisible from the ground. Millions of people visit every year, and almost none of them will ever lay eyes on the inscription crowning the whole thing.
6. The inside walls are covered in nearly 200 donated “memorial stones.”
As the monument went up, states, cities, foreign countries, churches, and private groups from all over the world sent carved blocks of stone to be set into the interior walls. There are now more than 190 of these commemorative stones lining the stairwell, a kind of scrapbook in rock. Donors range from U.S. states to foreign nations to fraternal organizations — even a few individuals. It turned the monument into a genuinely national, and international, collaboration, one quarried gift at a time.
7. A 5.8 earthquake cracked it open in 2011.
On August 23, 2011, a magnitude 5.8 earthquake centered in Virginia rattled the East Coast — and the Washington Monument took a real beating. Inspectors found more than 150 cracks, with some of the worst damage near the very top, and chunks of stone were shaken loose inside. The monument was shut to the public while crews rappelled down the exterior to inspect all four faces and patch the damage. It didn’t reopen until 2014, after roughly $15 million in repairs. An earthquake most people barely felt did serious harm to one of the sturdiest-looking buildings in the country.
8. Almost no building in the nation’s capital is allowed to tower over it.
Here’s where myth and reality meet. Many people believe there’s a law forbidding any D.C. building from rising taller than the Washington Monument. In truth, the city’s skyline is kept low by the Height of Buildings Act, which caps most structures at a height tied to the width of the street they face — generally far, far shorter than the monument’s 555 feet. The law wasn’t actually written to protect the monument’s view. But the effect is the same: thanks to those height limits, the monument still rises far above the rooftops of Washington, exactly as if the rule had been made for it.
9. Construction took nearly 40 years from start to finish.
The cornerstone was laid on July 4, 1848, but because of the long mid-century stoppage, the monument wasn’t structurally completed until late 1884 and wasn’t dedicated until 1885. That’s about 37 years from groundbreaking to ribbon-cutting. Plenty of people who attended the cornerstone ceremony as young adults were elderly — or dead — by the time the thing was finally finished. Few American landmarks have a construction timeline that spans an entire generation.
10. It’s still the tallest stone structure in the world.
The monument lost its “tallest building” title to the Eiffel Tower long ago, and modern skyscrapers dwarf it many times over. But here’s a record it still holds: at roughly 555 feet, the Washington Monument remains the tallest freestanding stone structure on the planet. Every taller building relies on steel or concrete skeletons. The monument is essentially a colossal stack of stone holding itself up — and more than 140 years later, nothing made of stone has ever risen higher.
Which one got you — the hidden message to God, or the earthquake that cracked it open? Forward this to the history buff in your life who thinks they know everything about D.C….
