Though only the Great Pyramid of Giza remains today, there were once Seven Wonders of the Ancient World (except perhaps the Hanging Gardens of Babylon, which may have never existed). Of the other six, none was smaller than the Statue of Zeus at Olympia, which measured only 39 feet high. That’s considerably less than the 455-foot height of the Great Pyramid.

Though St. Peter’s Basilica boasts an impressive dome with a diameter of 137 feet, the Roman Pantheon has an ever bigger dome which reaches a maximum width of 142 feet. The Pantheon once held the record for world’s largest dome, before it was overtaken by England’s Royal Albert Hall in 1871.

Germany’s Brandenburg Gate was built in 1788 and once marked the divide between East and West Germany. The historic gate stands 85 feet tall, which is smaller than a similar monument located in Paris known as the Arc de Triomphe. Commissioned by Napoleon in 1806 and completed in 1836, the Arc de Triomphe stands 162 feet high.

Though the 443-foot-tall London Eye was the first observation wheel to exceed 400 feet in height, the Dubai Eye and several other wheels have since surpassed it. Opened in 2021, the Dubai Eye is the tallest observation wheel in the world. Containing 48 rotating cabins, the wheel reaches an apex of 820 feet high.

Vienna’s elaborate Hofburg Palace is a 13th-century building that contains a whopping 2,583,339 square feet of interior space over 2,600 rooms. Buckingham Palace — the home of the British monarchy — is much smaller, containing 775 rooms encompassing a total area of 828,820 square feet.

The Louvre is the largest museum complex in the world. It covers 782,910 square feet and is home to over 38,000 works, including da Vinci’s “Mona Lisa.” The National Museum of China in Beijing isn’t far behind the Louvre, covering over 700,000 square feet of space.

Dating back around 5,000 years, Stonehenge is a mysterious monument comprising several dozen stone slabs formed into a circular formation. However, the Terracotta Army in China features significantly more individual pieces. Uncovered in the 1970s, this ancient Chinese landmark contains upwards of 8,000 individual life-sized soldiers plus even more stone horses and chariots.

While Niagara Falls is widely known for the incredible volume of water that it contains, the North American waterfall only reaches heights of 170 feet. Compare that to Angel Falls in Venezuela, however, which is the highest waterfall in the world with a 2,624-foot plunge that dwarfs Niagara’s height.

Located in Agra, India, the Taj Mahal was built by Emperor Shah Jahan in 1632 as a mausoleum for his wife. This impressive structure ascends to heights of 240 feet, though that’s not quite as high as the 315-foot-tall Elizabeth Tower in London — the clock tower that contains the famous bell known as Big Ben.

Though the Great Pyramid of Giza in Egypt is much taller than Mexico’s Great Pyramid of Cholula, the latter is significantly wider, giving it a total volume of 158 million cubic feet. The Great Pyramid of Giza boasts a volume of 92 million cubic feet. Archeologists believe construction of the Great Pyramid of Cholula began around 300 BCE but aren’t sure exactly who built it.

There are six separate canyons that comprise what’s known as Copper Canyon in Mexico’s Sierra Madre Occidental mountain range. The natural wonder reaches a maximum depth of 6,165 feet. The Grand Canyon in Arizona is only slightly smaller, descending to depths of 6,093 feet. The world’s deepest canyon, Yarlung Tsangpo Grand Canyon in Tibet, descends to a whopping 19,714 feet.

St. Peter’s Basilica in Vatican City is the largest church in the world, with an interior area of 163,200 square feet and an exterior area of 227,060 square feet. Located elsewhere on the Italian peninsula, the Milan Cathedral boasts a still-impressive total interior area of around 107,000 square feet, making it the largest church in Italy.

The White House and U.S. Capitol building are two of the most recognizable landmarks of Washington, D.C. The White House has a total floor area of around 55,000 square feet, but that pales in comparison to the U.S. Capitol, which contains an impressive 1.5 million square foot of floor area.

Overlooking the city of Rio de Janeiro, Brazil, Christ the Redeemer is a 125-foot-tall statue of Jesus Christ that boasts an impressive 92 foot wingspan from fingertip to fingertip. Located across the Atlantic in Pisa, Italy, the Leaning Tower of Pisa reaches heights of 186 feet. And if the tower wasn’t leaning, it would be even taller at around 197 feet.

Built for the 1962 world’s fair, the Space Needle is one of the most recognizable features of the Seattle skyline. But at 605 feet tall, the Space Needle is far from the tallest freestanding tower in North America. Toronto’s CN Tower is three times as tall, reaching a height of 1,815 feet and containing two observation decks that offer panoramic views.

With its striking orange hue, the Golden Gate Bridge is among the world’s most recognizable suspension bridges. It spans a total length of 8,981 feet over San Francisco Bay. Though it was once the longest suspension bridge in the world, the Brooklyn Bridge in New York City is much shorter than the Golden Gate Bridge, extending a total distance of 6,016 feet.

Of these two famous landmarks associated with Gustave Eiffel, the Eiffel Tower is taller, reaching 1,083 feet tall at its tip. That’s considerably taller than the Statue of Liberty’s height of 305 feet. The Statue of Liberty metal frame was constructed by Gustave Eiffel in the 1870s, and the famous French architect and civil engineer went on to build his namesake Eiffel Tower in the 1880s.

As of 2023, America’s National Park System is home to 63 national parks. Yellowstone National Park — located in Idaho, Montana, and Wyoming — is among the largest parks in the system, spanning an area of 2.2 million total acres. In comparison, Everglades National Park in Florida spans 1.4 million acres. The largest U.S. national park is Alaska’s Wrangell-St. Elias, which covers 8.3 million acres.

With 104 floors and an official height of 1,776 feet, One World Trade Center is the tallest building in New York City — and the Western Hemisphere. The Empire State Building is a close competitor for total number of floors, with 102. However, the Burj Khalifa in Dubai dwarfs them both, featuring a whopping 163 floors.

Soaring 630 feet above St. Louis, the Gateway Arch is the tallest monument in the U.S. Dedicated to America’s westward expansion, the monument was designed by architect Eero Saarinen and opened to the public in 1967. The Washington Monument in Washington, D.C. reaches heights of 554 feet, though it was once the world’s tallest structure until 1889.
