Quick — name a famous landmark. Chances are you said something along the lines of the Eiffel Tower, the Statue of Liberty, or even the Taj Mahal. These iconic sights are practically engrained into the popular culture, yet here’s a follow-up: can you name something about them? This, it seems, is where most people draw a blank.

Sure, saying that they’re “big” or “really cool” technically answers the question, yet wouldn’t you rather dive a little deeper into the storied histories of these beloved monuments? Don’t bother reaching for a textbook, because these little-known details about the world’s most iconic landmarks will make you look like a regular history buff on your next vacation.

1. The Leaning Tower of Pisa: During the early stages of its construction, the Leaning Tower of Pisa actually leaned in the opposite direction. It wasn’t until more layers were added that the tower began tilting southward.

2. Mt. Fuji: Though its peak may look peaceful, Mt. Fuji is actually a stratovolcano — three volcanoes stacked into one! It’s still an active volcano, too, though the last time it erupted was 1707.

3. The Great Wall of China: Measuring 13,170.70 miles, the Great Wall spans half the length of the equator. Considering it took more than 2,000 years to build, it’s no surprise that the Great Wall remains the most significant feat of human engineering ever.

4. Machu Picchu: How the Incas managed to build Machu Picchu continues to puzzle historians, as the stones used to create the citadel weigh dozens of tons. Some believe they pushed the stones up the cliff sides themselves; others posit that they carved the stronghold into the mountain.

5. The Great Sphinx of Giza: Believe it or not, the Great Sphinx isn’t a sphinx at all. In classical depictions, a sphinx has the body of a lion, the head of a woman, and the wings of a bird; technically, the Great Sphinx is an androsphinx.

6. The Golden Gate Bridge: While it’d be hard to imagine the Golden Gate Bridge as any color other than red, it was originally supposed to be painted with blue-and-yellow stripes. Upon seeing the red-painted girders, however, the consulting architect changed his mind.

7. Big Ben: Though most of us refer to it as “Big Ben,” the clock tower that sits on the end of the Palace of Westminster is actually called the Elizabeth Tower — it’s the bell inside that’s called “Big Ben.”

8. The Taj Mahal: Commissioned in 1632, the Taj Mahal cost an estimated 32 million Indian rupees to build, equivalent to over US $1 billion at the time. Even with more than 20,000 laborers at work, it took 22 years to complete the mausoleum.

9. Times Square: Originally named for The New York Times newspaper, Times Square sees around a million people pack into its streets each New Years Eve to watch the ball drop. All told, over 50 million tourists visit this slice of New York City each year.

10. The Louvre: Originally constructed as a fortress in 1192, the Louvre is now the biggest museum in the world. In fact, it would take you about 100 days to walk every inch of the museum and take note of every piece inside.

11. Christ the Redeemer: In the wake of the separation of church and state following the founding of the Brazilian republic, Brazilian Catholics feared the country was becoming increasingly godless. Christ the Redeemer was the church’s answer, taking nine years and over six million stone tiles to complete.

12. Mt. Rushmore: Sculptor Gutzon Borglum originally conceived of Mt. Rushmore depicting the faces of great western heroes, including Lewis and Clark and Buffalo Bill Cody. He eventually settled on a more nationally unifying theme with the faces of Washington, Jefferson, Roosevelt, and Lincoln.

13. The Eiffel Tower: Though the iconic landmark bears the name of French engineer Gustave Eiffel, he actually wasn’t the one who designed it. It was Maurice Koechlin and Emile Nouguier, two of Eiffel’s employees, that drafted the original blueprint for the tower.

14. The Trevi Fountain: Roughly $3,300 worth of coins are tossed into the Trevi Fountain each day. Those coins are then scooped out every night and donated to charities that seek to feed the homeless of Rome.

15. The Statue of Liberty: Despite the belief that Lady Liberty was a gift from France, the U.S. actually had to pay for most of its construction. Additionally, Boston and Philadelphia originally petitioned to host the statue, though in the end, New York won out.

16. The Colosseum: Constructed over ten years, Rome’s famous Colosseum could hold 50,000 spectators in its heyday. This seating capacity probably came in handy, as some festivals and events could last up to 100 days at a time!

17. Buckingham Palace: Originally, Buckingham Palace was known as Buckingham House, the home of the first Duke of Buckingham John Sheffield. It wasn’t until Queen Victoria assumed the throne in 1837 that the house became the official royal residence.

18. Burj Khalifa: The tallest building in the world, the Burj Khalifa is three times as tall as the Eiffel Tower. If its pieces were laid end to end, the tower could stretch more than a quarter of the way around the globe.

19. Sydney Opera House: Jørn Utzon, the Danish architect that proposed the opera house’s current design, originally had his blueprint rejected three times. It wasn’t until renown American architect Eero Saarinen praised the design that it was ultimately selected.

27. Thor’s Well (Cape Perpetua, Oregon): Often referred to as the Drainpipe of the Pacific, the 20-foot sinkhole located just off the Oregon coast looks like it’s draining the sea. (Don’t worry—it’s not!) Still, it provides perfect photo opportunities for those brave enough to venture near it.

28. Prada Art Installation (Marfa, Texas): Does anything say Texas quite like a $120,000 “pop architectural land art project” of a designer Italian shoe store? Maybe. But you won’t find anything like this anywhere else in North America.

29. The Desert of Maine (Freeport, Maine): The flat sands of America’s northeastern-most state beckon those who’ve already stuffed themselves to bursting with lobster. Though not a true desert, the 40 acres of glacial silt is close to the real thing.

30. Cadillac Ranch (Amarillo, Texas): Ten Cadillacs half-buried off Route 66 comprise this Texas art project. It not only welcomes vandalism and drive-by paint jobs from visitors, but it encourages anyone to add a touch of paint.

33. M-185 (Mackinac Island, Michigan): Michigan banned motor vehicles from this eight-mile stretch of road that wraps around the popular tourist island in Lake Huron. The law was passed in 1898 after a doctor’s car scared some horses and people complained.

34. Eiffel Tower (Paris, Texas): If you want to see the Eiffel Tower, the City of Lights might be calling your name—but a city two hours outside Dallas might be calling out, too. And this Eiffel Tower has a cowboy hat on top!

35. Monowi (Monowi, Nebraska): As of the 2010 census, just one person called the .21-square-mile city home. The lone occupant? A 76-and-a-half-year-old woman living alone. The village peaked in 1930 with a population of 150.

38. Newby-McMahon Building (Wichita Falls, Texas): After a nearby oil boom, J.D. McMahon collected investments for a skyscraper to house the influx of people.

43. Point Roberts (Point Roberts, Washington): You have to travel through 25 miles of Canada to get to this United States city, which was created when the U.K. and the U.S. determined the 49th parallel would form the border between the countries. But they overlooked the southernmost tip of the Tsawwassen Peninsula!

44. Sam Kee Building (Vancouver, British Columbia, Canada): Too stubborn to sell his lot of land after the city expropriated 24 feet of his property, Sam Kee built the world’s shallowest commercial building—just five feet deep on the bottom floor.

45. Grave of Mary Ellis (New Brunswick, New Jersey): A local spinster died in 1828 and was buried in a site that eventually became the parking lot for an AMC movie theater. The grave is probably more interesting than most movies playing at the theater, to be honest.

46. Moonlight Towers (Austin, Texas): Before the streetlight boom of the 20th century, cities posted arc-lamps way up in these towers to illuminate multiple blocks at once. Though all but eliminated from North America, Austin still boasts a few 165-foot towers.

47. Bubblegum Alley (San Luis Obispo, California): A piece of chewed gum stuck to a wall may not be your interpretation of sightseeing, but what about thousands of pieces of chewed gum stuck to over 2,000-square-feet of alleyway walls?

Jets Like Taxis

48. Jerimoth Hill (Foster, Rhode Island): At 812 feet high, this rock slab is the highest peak in all of Rhode Island. Hikers who “braved” the .3-mile trail with a 10-foot elevation gain to reach the peak often stack stones on top to make the point that much higher.
