Empire State Building

We’ll begin with what’s perhaps the most famous skyscraper in "The City That Never Sleeps". The Empire State Building speaks to the magnificence and grandeur of New York City: After all, it is named after the State of New York’s official nickname, "The Empire State".

At the time of its construction, the Empire State Building was the tallest building in the world, a title held for almost 40 years. Its exquisite Art Deco design and innovative architecture have turned it into an instantly recognizable icon. Perhaps more famously, it has been featured in unforgettable pictures like "Sleepless in Seattle" and "King Kong". Be honest: Whenever you see a picture of this building, can’t you almost see a humongous ape perched atop its antenna?

Flatiron Building

For many, the most remarkable feature of this iconic building is its unusual name, which comes from its also rather unusual shape. The Flatiron is considered a New York City institution, and its history is almost as inspiring as its groundbreaking design.

In its early years, the Flatiron was known by the derisive nickname "Burnham's Folly", since detractors believed that architect Daniel Burnham’s design was a laughable idea. History would prove Burnham right though, since the Flatiron is still one of the most instantly recognizable skyscrapers in the world.

Willis Tower

For any Chicagoan who might be reading this, we know that you probably still call this building the "Sears Tower", but we thought it would be appropriate to include the official new name of this iconic skyscraper. Located in the heart of the "Loop", the Willis Tower is a 110-story, 1,451-foot building that has truly earned its place in Chicago’s skyline.

Since its opening in 1973, Willis Tower has proudly held the title of the world’s tallest building for close to 25 years. Regardless, this juggernaut is still an American landmark and one of Chicago’s most visited tourist attractions.

Transamerica Pyramid

While most pictures of San Francisco’s skyline are usually dominated by the Golden Gate Bridge, visitors of "The City by the Bay" are frequently dazzled by this unusual yet breathtaking building. Completed in 1972, the Transamerica Pyramid was San Francisco’s tallest building until 2018, when it was surpassed by the Salesforce Tower.

Without a doubt, the most striking aspect of this building is its groundbreaking design: Just like San Francisco’s carefree spirit of independence, this building seems effortlessly innovative. It has been compared to other revolutionary designs, most notably to "the Shard" building in London.

Columbia Center

Formerly known as "the Bank of America Tower" (or BOAT for short), the Columbia Center was constructed in downtown Seattle in the early ‘80s: At the time, this imposing black skyscraper was the highest building on the West Coast. While most of this skyscraper is leased for private usage, it does house the highest public viewing area west of the Mississippi River.

The Columbia Center’s design produces a rather interesting effect: Since the building is composed of 3 separate segments joined by 2 setbacks, viewers from the street might believe the Columbia Center is made from 3 different towers set side to side.

The Chrysler Building

As you probably expected, many iconic skyscrapers from "The City That Never Sleeps" will be featured in this article. The Chrysler Building is an art-deco masterpiece located at the intersection of 42nd Street and Lexington Avenue, which holds the distinction of being the world’s very first supertall skyscraper.

This building was commissioned by (and named after) Walter Chrysler, head of the Chrysler Corporation, and its construction was marked by a friendly competition with the Empire State Building for the title of the world’s tallest building. In that sense, the Chrysler Building’s remarkable 1,046 feet height gave it this impressive title, albeit only for 11 months.

Wells Fargo Plaza

If you ever find yourself taking a stroll through Downtown Houston, you’ll definitely come across a gorgeous all-glass skyscraper. You can’t miss it: After all, the Wells Fargo Plaza is the tallest all-glass building in the entire Western Hemisphere, standing at an impressive 992 feet.

This skyscraper was formerly known as the Allied Bank Plaza and in, 1988, it was renamed to the First Interstate Bank Plaza. However, when in 1996 First Interstate Bancorp was bought by Wells Fargo, this skyscraper changed its name once again to the Wells Fargo Plaza we all know.

John Hancock Center

Founding Father John Hancock truly deserves all the praise it can receive from the American people, so it stands to reason that he should have his name honored by a 1,128-foot supertall skyscraper. Located in the iconic "Magnificent Mile", the John Hancock Center was for a while the tallest building in Chicago, surpassed by the previously mentioned Willis Tower.

This skyscraper was completed in 1969 and it has remained a Chicago staple ever since. It houses several restaurants and offices, as well as approximately 700 condominiums. Interestingly, the John Hancock Center is the background on which the 1988 horror film "Poltergeist III" takes place: Posters for this film featured this skyscraper, with a menacing lighting bolt crossing the night sky behind it.

Bank of America Plaza

Just like the Empire State and the Chrysler buildings, the Bank of America Plaza is another wonderful example of Art Deco architecture located between Midtown and Downtown Atlanta. This gorgeous skyscraper is instantly recognizable thanks to its unusual color palette, and it holds the distinction of being the tallest building of any U.S. state capital.

If you are lucky enough to visit "the City in a Forest", try to visit the Bank of America Plaza at night. You’ll quickly notice that the stunning golden spire at the top of the building (which is actually shaped like the Plaza itself) glows alongside a gorgeous pyramid of girders, in a lovely orange hue that tries to resemble old street lights.

Home Insurance Building

We’ll end this article by honoring an iconic skyscraper that, while it is not still standing, lives on in the proud history of our country. Standing at 138 feet, the Home Insurance Building might not seem remarkably tall by today's standards but, at the time of its construction in 1885, this Chicago historical landmark became the world’s very first skyscraper.

Due to a decrease in its occupancy, the Home Insurance Building was demolished in 1931, alongside 5 other buildings, to make way for the site on which the Field Building now stands. However, this landmark’s legacy still stands, earning its well-deserved place in history as the father of the skyscraper.

Yellowstone National Park, created in 1872, is a vast natural forest of 3,500 square miles that spans the states of Wyoming, Montana, and Idaho. More than half of the world's geothermal phenomena can be observed here , with some 10,000 different examples. It also has more than 300 geysers, which is about two-thirds of all the geysers on the planet.

This location, the first national park in the United States, has been a World Heritage Site since 1978. It is also known for protecting abundant and diverse wildlife —such as grizzly bears, wolves, bison, and wapiti— and for drawing millions of visitors from all over the world each year. And you, have you ever been?

The Independence Hall, located in historic Philadelphia, was designated a World Heritage Site in 1979. This location, far more than just a building, is considered the birthplace of America’s political foundation . The Assembly Room of the Pennsylvania State House, now known as Independence Hall, is where the Declaration of Independence was signed in 1776. And just 11 years later, the United States Constitution was also debated and signed here.

This Georgian-style red brick structure was designed by Scottish lawyer Andrew Hamilton and completed in 1753 to house the colonial assembly of the Province of Pennsylvania. In the 19th and 20th centuries, it was then renovated several times. In 1966, the building was recognized as a National Historic Landmark by the U.S. government and is currently the centerpiece of the Independence National Historical Park.

Statue of Liberty

Installed in 1886 at the gate of New York’s harbor, the Statue of Liberty has since welcomed millions of immigrants who have come to populate the United States. This colossal neoclassical 305-foot-tall effigy enlightening the world with its torch was made in Paris by the sculptor Frédéric Auguste Bartholdi in collaboration with Gustave Eiffel. It was a gift from France to our country on the occasion of the centenary of our independence.

To visit this historic monument, declared a UNESCO World Heritage Site in 1984, tickets must be purchased in advance. Or you can always ride the fare-free Staten Island ferry and admire it from afar in all its splendor!

Located in the southwest of Colorado, the Mesa Verde Plateau reaches an altitude of over 8,500 feet. The National Park was established in 1906 and was added to the list of American World Heritage Sites in 1978. This location hosts a large number of Pueblo Indian dwellings built between the 6th and 12th centuries. Some 4,400 settlements have been found , including villages built high up on the plateau and imposing stone-built homes on rocky outcrops, with more than a hundred rooms in some cases.

The Mesa Verde National Park, which nowadays protects these invaluable archaeological sites, is a testament to the ancient cultural traditions of Native American tribes and is among the best preserved in the United States. If you haven’t visited yet, you must! We guarantee you a spectacular window into the past!

Hawaii Volcanoes National Park is located on the southernmost Hawaiian island and was founded in 1916. It is best known for its extraordinary biodiversity spread over more than 340,000 acres, and it is in fact thanks to this natural richness that UNESCO declared it a World Heritage Site in 1987.

The park, as you would have guessed, is home to several volcanoes . Although many of them are currently inactive, two are very much alive: Mauna Loa , which last erupted in 1984, is known to be still active and is considered the world's greatest volcanic mass; Kīlauea is more than 200,000 years old and has been erupting since 1983, the most recent occurring on June 3, 2024.

If you are considering visiting the park, exploring the volcanoes, and enjoying a unique experience, we also recommend a museum tour , where you can learn all about the history of these fascinating fiery peaks.

Monticello and the University of Virginia

Image: Richard Hedrick

The Monticello Residence in Virginia, designed by Thomas Jefferson, the third president of the United States, is one of the finest examples of American neoclassical architecture . Since 1987, it has been on the UNESCO World Heritage List, along with the University of Virginia in Charlottesville.

Jefferson created Monticello as his plantation mansion and envisioned the university as the ideal ‘academic village’ . His vision of architecture, based on classical antiquity, reflects not only his aspirations for a new American republic heir to the European tradition but also the degree of cultural experimentation that could be expected of a country in the process of democratic evolution.

Papahānaumokuākea, made up of a series of 583,000 square miles of small islands, atolls, and surrounding marine wilderness, is located in northwest Hawaii. This particular location has enormous natural value as one of the largest marine protected areas in the world . It is equally important for its Native culture. Two of its islands, Nihoa and Makumanamana , bear archaeological remains that attest to the presence of human settlement even before the arrival of Europeans . For Hawaiians, this site has cosmological significance , as it represents the bond between humans and nature.

Papahānaumokuākea was designated a World Heritage Site in 2010, and although it’s not currently open to the general public, it continues to be accessible for research, habitat restoration, and cultural and educational purposes.

Grand Canyon National Park is known as one of the seven natural wonders of the world and has been a UNESCO World Heritage Site since 1979.

Located in the state of Arizona, this park is divided by a gigantic steep-sided canyon carved by the Colorado River, which, at more than 6,000 feet deep, is the most spectacular gorge in the world . This site is so relevant that all the geological history of the last two billion years can be found in its horizontal strata. And across its 277 miles, there are even traces of prehistoric man's efforts to adapt to a particularly inhospitable environment .

If you haven’t visited it yet, you should soon join the more than 5 million people traveling each year!

San Antonio Missions

Image: USA-Reiseblogger

This 2015 World Heritage Site, built on what was once the border of New Spain along the San Antonio River, constitutes five mission complexes that reflect the history of the region.

Founded by Franciscan missionaries in the 18th century, San Antonio includes architectural structures, archaeological remains, churches, dwellings, farmland, silos and water supply systems .

This site, located in Texas, is a living testament to the Hispanic monarchy's enterprise to colonize, evangelize, and defend the northern frontier territories of New Spain. These missions are also an example of the mixture of Hispanic and Coahuila culture , as can be seen in the ornamental elements of the churches that mix Catholic symbolism with native naturalist aesthetics.

The 20th-Century Architecture of Frank Lloyd Wright

Image: Yuhan Du

This series of eight Frank Lloyd Wright works recognizes the famous architect's influence on modern design . The most relevant buildings included in the 2019 Unesco designation are Fallingwater House in Mill Run, Pennsylvania; Unity Temple Church in Oak Park, Illinois; Herbert and Katherine Jacobs House in Madison, Wisconsin; and the Solomon R. Guggenheim Museum of Art in New York City, among others.

These sites are a great example of the ‘organic architecture’ conceived by Wright, characterized by open plan design, the blurring of the boundaries between inside and outside, and the highly original use of materials such as steel and concrete . Wright's innovative conception of architecture, whether in residential, work, cultural, or religious buildings, greatly influenced the evolution of modern architecture in Europe and the United States and is still a point of reference for designers today.

The abandoned film set of Spectre from Big Fish still stands on a private island along the Alabama River. Originally built for the 2003 movie, the town was left behind after filming and has slowly decayed.

Fires and flooding destroyed much of it, but a few buildings, spooky trees, and crumbling columns remain, giving the site a haunting atmosphere.

Dogpatch USA, Arkansas

Dogpatch USA, a hillbilly-themed park in Arkansas based on the Li’l Abner comic strip , opened in 1968 but never met visitor expectations. With low-key attractions and rustic charm, it struggled to draw crowds and ultimately closed in 1993.

Attempts to sell the land largely failed, and parts of the park still stand abandoned. While some parcels have been sold over the years, most of the site remains a curiosity for urban explorers.

Custer Ghost Town, Idaho

Image: Ruth Durbin

Custer, Idaho, was born from the 1870s gold rush, and later grew after a fire destroyed the nearby town of Bonanza. As mining dried up, the once-busy one-street town was abandoned, leaving behind rusted equipment and relics like a bullet-riddled poker table.

Thanks to its designation as a historic site in 1981, parts of Custer have been restored. Summer visitors can tour cabins, a schoolhouse, and the old saloon.

At the southern tip of Illinois, Cairo once thrived as a key port town during the steamboat era and later as a railroad hub. But as industry shifted and economic opportunities dwindled, the city entered a long period of decline.

Today, Cairo is eerily quiet. Its historic downtown is filled with crumbling buildings and boarded-up windows , and decay is spreading into nearby neighborhoods.

Knightridge Space Observatory, Indiana

Image: Daniel Gregoire

Hidden in the woods near Bloomington, Indiana, the Knightridge Space Observatory was built in the 1930s for early astronomers . Its wooden dome once held a four-ton telescope, but city growth and light pollution made it obsolete.

Abandoned since the 1960s, the building was left to decay, with its dome rusted shut, the floors unstable, and the telescope relocated. It has since been demolished due to safety concerns.

Jazzland, Louisiana

Image: Dmitry Lakhno

Jazzland was a theme park in New Orleans that opened in 2000. After major investments, it reopened in 2003 as Six Flags New Orleans. Following Hurricane Katrina in 2005, the park was submerged, with murky floodwaters destroying roughly 80% of the property. Rides were wrecked, stands overturned, and only the Batman coaster survived on higher ground .

Deemed too costly to repair, the park was abandoned and now draws curious urban explorers.
