This is one of the oldest continuously occupied public buildings in the United States. Built in 1610 , it served as the seat of the Spanish, Mexican, and, finally, American government.

Some experts claim that the key to its longevity is the material of which it is composed. Adobe has always worked very well as a building material in areas that, like New Mexico, have a major thermal amplitude. This is because adobe works as a thermal insulator.

Besides all the historical artifacts this building holds, it also has many stories to tell. In 1862, during the Civil War, Abraham Lincoln gave a famous speech from the Palace's balcony.

Built around 1637 by English immigrant Jonathan Fairbanks in what is now Dedham, Massachusetts, many sources claim that the Fairbanks House is the oldest timber-frame house in America.

With so many years of existence and so many people who must have passed through it, can you imagine the stories that could be told from inside those wooden walls? For 8 generations, Jonathan's descendants inhabited this place, and today, it functions as a museum for all of us to visit.

This 380 -year-old house was built with oak wood, straw, animal fur, and other materials of the time. Just imagine how cold it must have been inside during winter!

Can you imagine holding an object from the 1590s in your own hands? Well, that's what you could do at the C. A. Nothnagle Log House in New Jersey.

The Finns and the Swedish left testimonies of their building techniques in our territory with this log cabin built between 1638 and 1643, one of the oldest still extant in the country. The many inhabitants of this house never had to worry about winter; the interior features a large, centrally located stone and brick chimney that provides even heat for the entire place.

With so many years of history, it's not unusual for visitors to experience strange episodes at the C. A. Nothnagle Log House. Some have reported hearing footsteps and soft murmuring, while others affirm to have seen a specter of a woman dressed in colonial-era clothing.

Richard Sparrow, surveyor and early settler of Plymouth, Massachusetts, built this historic house in 1640, making it the oldest surviving house in Plymouth.

With its timber frame, this house is an example of typical colonial architecture, demonstrating the durability of this type of construction. Despite the restorations necessary to keep it standing, the house keeps most of its original materials and still looks much as it did in the 17th century , making it an interesting source of education about the period.

The Fairbanks House is not the only historic house in Massachusetts.

Considered a colonial mansion, the Turner-Ingersoll Mansion was built in 1668 for Captain John Turner and stayed with his family for three generations. The place became famous in 1851 for its appearance in Nathaniel Hawthorne's Gothic novel "The House of the Seven Gables," which also gave it its characteristic nickname.

While the dark stories Hawthorne wrote about are fictional, some visitors claim to have felt a scary feeling and strange vibes inside the house. Would you like to visit the museum?

As the name implies, this historic house was the home of patriot Paul Revere.

Built in 1638 , it is not only one of the oldest houses in the country, but it is also the oldest standing building in downtown Boston, and represents a fine example of classic Colonial American architecture.

The building originally belonged to another owner, and Paul Revere acquired it around 1770 . If you visit the house, you can see objects and artifacts that actually belonged to the Revere family! You won't be the first, though, as an estimated 300,000 people visit the house annually.

Shirley Plantation is undoubtedly one of the oldest and most famous plantations in America.

While the plantation was founded in 1613, construction of its main house began in 1723, designed in the Georgian architectural style.

Additionally, visitors can find artifacts, tools, and weapons from the Civil War era, making it a truly valuable experience. As another detail, Shirley Plantation also has the oldest known plantation portrait in America: it features Elizabeth Hill and John Carter, whose marriage united the Hill and Carter families. These families have owned the place since 1738 to this day!

Susanna Wright was a pioneer Quaker woman from Philadelphia, who decided to live in Wright's Ferry (what is now Columbia) in the early 18th century. Wright was active in poetry, science, and local politics and business.

In 1738, she built Wright's Ferry Mansion, which served not only as her family home but also as a business center. With its classic proportions and elegant style, the mansion is today one of the oldest in the country. It was preserved to keep its original appearance, remaining a fine example of early 18th-century architecture in the country.

Legend has it that the house is haunted by the spirit of its original owner, with several visitors claiming to have seen her, or heard murmurs and loud footsteps inside the house.

Mount Vernon (Virginia, 1734-1750s)

Image: Matt Briney

We can't overlook the iconic Mount Vernon. Built in Fairfax County, Virginia, it’s one of the most famous homes in the country. And you know why: it was the home of our first president, George Washington.

The original house was built in 1734 by George Washington's father, Augustine Washington, and then expanded by his son into the building we see today. Washington influenced American architecture with the design of this building. In fact, it is said that the design of the "New Room" in Mount Vernon inspired the White House's Oval Office!

While the exterior is made of wood, it was sanded and beveled to mimic stone for a classic, elegant style. The house also has Martha Washington's famous "Blue Room," one of the most beautiful and best-decorated spaces, which still preserves its appearance. Have you already visited it?

Charleston, South Carolina, was the site where the historic Drayton Hall was built between 1747 and 1752.

This 18th-century plantation is considered to be one of the best-preserved examples of Georgian architecture. In addition, it is also claimed to be the only plantation house on the Ashley River that survived the Revolutionary and Civil Wars, not without some damage.

With nearly 300 years of history, it's undeniable that this house was the scene of many stories and events. Some visitors have claimed that the house is haunted , reporting sightings of apparitions and hearing mysterious noises. Spooky, isn't it?

In 2015, a time capsule from 1944 was found beneath the City Hall stairs in Lebanon, New Hampshire. Inside was a whiskey bottle with a humorous note: "Whoever finds this bottle may keep it. Sorry, there is no liquor in it, but I drank it all up."

The note was signed by Samuel Stevens, a former city surveyor. Along with the bottle were old newspapers and a penny, but Stevens’ decades-old joke stole the spotlight.

In 1958, a time capsule was buried at a former state hospital on the west side of Indianapolis. It included a video from the Bahr Treatment Center's groundbreaking ceremony, which focused on mental health care.

Though some audio is lost, the video references electroshock and insulin shock therapy . The footage is a somber reminder of how far mental health treatment has progressed.

During renovations, a Niagara Falls funeral home discovered a 1948 time capsule. It held typical items like newspaper clippings, letters, and postcards.

But one surprise stood out: a piece of cake, possibly from the building's opening party .

In March 2015, a 19th-century time capsule was found in the cornerstone of a former telescope factory in Pittsburgh. It included what may be one of the first pieces of optical glass made in America .

The Brashear Company, founded by astronomer Dr. John A. Brashear, made telescopes and scientific tools from the 1880s to the early 1900s. By the 1940s, the site was used to produce bombsights for the U.S. military.

In 1983, Steve Jobs spoke at the Aspen Design Conference and added a computer mouse to the Aspen Time Tube , buried nearby. Meant to be opened in 2000, its location was forgotten over time.

In 2013, a National Geographic crew finally unearthed it. Along with the Lisa mouse, the capsule held a Rubik's Cube and a Moody Blues 8-track tape.

While technically, this is not a time capsule in strict terms, it can be seen as one. An American family inherited an old building from their grandparents and discovered a forgotten shoe store locked for decades .

The store, active from the 1940s to 1960s, held hundreds of vintage shoes in mint condition, possibly worth thousands. The family is keeping the location secret while they assess its full value.

Inspired by Egyptian tombs, Dr. Thorwell Jacobs of Oglethorpe University created a massive time capsule called the "Crypt of Civilization."

Buried beneath the school, it holds items like a Gone with the Wind script, recordings, plastic toys, an English-teaching machine, and a sealed Budweiser . It’s meant to be opened in the year 8113 AD.

In 2016, a time capsule from Montgomery Elementary in Albuquerque was found, containing notes from a 1968 fourth-grade class. Most messages were typical for kids at the time. But one stood out: Greg Lee Youngman began his note with "I am dead" and claimed he was born in 1900 . Whether he was imagining the distant future or pretending to be a ghost, it added a spooky twist.

While demolishing his parents' old barn, a man discovered a 128-year-old time capsule hidden beneath the rubble.

Inside were a Mason jar, a newspaper from August 10, 1894, an almanac, a damaged notebook or storybook, and a single black shoe .

How the White House gained its name

Originally, the building was called the "President’s House." That only changed after the 1814 fire. During the War of 1812, British troops marched into Washington and set many buildings on fire, including the main one.

Walls were scorched, and smoke damage lingered inside and outside the building. When repairs began, painters coated the building white to cover the burn marks . This resulted in the "White House" nickname. Nearly a century later, Theodore Roosevelt made it official.

A hidden underground beneath America’s books

Have you ever heard of the Library of Congress's underground tunnels? Most visitors never see them or learn about them. They connect their buildings, allowing staff to transport rare books and documents safely and efficiently. Fragile, valuable materials had better be protected from the weather, the sunlight, and, well, the people!

3

The Golden Gate Bridge wasn’t supposed to stay red

The reddish color of the Golden Gate Bridge (officially named "International Orange") was supposed to be a temporary priming coat to protect the steel.

However, when engineers looked at the bright color peeking through the fog against the stunning blue and green of the San Francisco Bay, they said, "You know what?" It should stay like that. The Navy proposed painting it black and yellow, but it was never done. The stunning color turned it into one of the most iconic buildings in the world.

The Empire State Building wanted to welcome airships

Back in 1931, the Empire State Building’s spire was intended as a mooring mast to serve as a docking station for airships. The idea was that passengers should be able to step directly into Manhattan from the sky!

Sure, it was a futuristic plan, but it was eventually dismissed for being wildly dangerous. Passengers would have had to climb out at dizzying heights in strong winds. Not ideal! And certainly not glamorous.

5

The famous ceiling that got the stars wrong

You may have seen images of Grand Central Terminal’s celestial ceiling —or seen it with your own eyes. But there’s a twist: Did you know that the constellations in it are painted backward?

The way they are represented is as if viewed from outside the universe, rather than from Earth. Whether it was a mistake by the artist or it was an intentional reverse on cosmic perspective, the terminal ceiling has looked like this since its opening in 1913.

6

The president who quietly ran a whiskey empire

George Washington is remembered as a general and a president, of course. But he was also a major whiskey producer. Hidden on the grounds of Mount Vernon was a fully functioning distillery, built in the late 1790s.

By the time of Washington’s death, it was producing nearly 11,000 gallons of whiskey a year. That made him one of the largest distillers in the young United States!

7

The iconic façade didn’t exist during the battle

When you think of the Alamo, you surely picture its iconic façade. However, that structure was not part of the original mission!

During the famous 1836 battle, the building looked far simpler, and it lacked its now-famous curved top. That façade was added decades later by the U.S. Army when the structure was used as a supply depot

8

Why visitors can no longer climb to the torch

Did you ever hear some old relative’s anecdote ot climbing all the way to the top of Lady Liberty’s torch? They weren’t lying: Up until 1916, visitors could. However, around that time, some explosions in a nearby munitions depot sent shockwaves through the statue.

The blast damaged the torch and weakened its structure. For safety reasons, access was permanently closed to the public.

9

The concrete that is still hardening today

The Hoover Dam contains so much concrete that it generates heat as it cures. Engineers knew that if poured as one solid mass, it would take more than a century to cool and could crack.

Instead, they built it using interlocking concrete blocks, each cooled with circulating water. Even so, parts of the dam are still slowly curing today.

10

The building that accidentally cooked its neighbors

When the Walt Disney Concert Hall opened in Los Angeles, its gleaming metal exterior stunned visitors. But it also caused an unexpected problem…

The highly reflective steel panels bounced sunlight onto nearby sidewalks and apartments. In some spots, the glare was so intense that it melted materials! As a result, engineers eventually had to dull parts of the surface.

11

The Capitol’s dome isn’t stone

The grand, massive dome atop the U.S. Capitol looks like solid stone, doesn’t it? But, in fact, it is made of cast iron.

In the mid-1800s, stone was considered too heavy and expensive for such an ambitious structure. Cast iron allowed builders to create a taller, more ornate dome that weighs nearly nine million pounds.
