Boeing doesn’t just make jumbo jets, they also make jumbo buildings. Their factory in Everett, Washington, is an architectural marvel — it’s not only the largest building by volume in America but also the world, as of 2022. The plant covers 98.3 acres with an interior measurement of 472 million cubic feet, containing its own fire department, bank, and water treatment plant.

Domes are generally synonymous with state capitol buildings, but only Maryland’s is made from wood. Other states with unique domes include the zinc dome of the Illinois state capitol, the brick-and-concrete dome found in Washington state, and the terra cotta domes found atop the buildings in Kentucky and Pennsylvania. The newest dome belongs to Oklahoma's capitol, added in 2002.

The Cathedral of San Juan Bautista was first built in 1521, though its current structure dates to 1540 — which still makes it the oldest church on U.S. soil. The oldest church founded in the 50 states is the San Miguel Mission in Santa Fe, New Mexico, which was built in 1610.

On the front of the $100 bill is the face of Benjamin Franklin. On the back is Independence Hall, one of Philadelphia's most famous buildings. Completed in 1748, Independence Hall (originally the Pennsylvania State House) was built in the Georgian style of architecture. The historic site is where the Declaration of Independence and the U.S. Constitution were both debated and adopted during the founding of the United States.

Connecticut’s famous Glass House was completed in 1949 based on designs by architect Philip Johnson. The iconic building's construction includes minimalist structure, geometry, and proportion, but is notably built with walls of glass. As a masterful publicity stunt, Johnson then moved into his Glass House, living there from 1949 until his death in 2005. The building is often seen as a companion piece to Mies van der Rohe's similar Farnsworth House.

The Cadet Chapel is found on the campus of the U.S. Air Force Academy in Colorado Springs, Colorado. The all-faith center of worship features 17 aluminum, glass, and steel spires that shoot 150 feet into the sky and vaguely resemble the noses of airplanes. Completed in 1962, the Cadet Chapel is now the most-visited human-made tourist attraction in the state.

In the early 1800s, French artist Pierre Charles L’Enfant worked with George Washington on an idea for a President’s Palace four times bigger than the modern White House. Irish architect James Hoban later proposed a more modest neoclassical design based on the Leinster House in Dublin, which ultimately won. Hoban had also previously constructed a neoclassical building in South Carolina which Washington liked.

One of the nation’s most distinctive state capitol buildings, the Nebraska State Capitol was the product of a nationwide design competition in 1920. Clad with Indiana limestone, the building has a wide base with a 400-foot domed tower at its center. On top of that is a 19-foot-tall bronze figure called "The Sower.” When it was finished in 1932, it was the tallest building in Nebraska; it ranks third today.

The Iolani Palace in Hawaii was once the home of King Kamehameha III and Queen Liliuokalani, two of the most important rulers of the Kingdom of Hawaii in the mid-19th century. Before their reign was ended by U.S. colonization, the Hawaiian leaders ruled from their palace in Honolulu. The building still stands today, making it the only royal palace in the United States.

The distinctive canopy-style roof of Denver International Airport's main terminal, which debuted in 1995, was designed in just three weeks. Not only did the design evoke the Rocky Mountains of Colorado, but it also saved the airport more than $100 million in budget by sparing thousands of tons of steel. It’s a memorable welcome for the millions of travelers who pass through the airport each year.

Known locally as "The Big Basket," the Longaberger Basket Building opened in 1997. The building is a scaled-up model of the Longaberger company's Medium Market Basket. Though Longaberger closed its doors in 2018, the building remains one of Ohio's most recognizable architectural icons. Its giant handles, though non-functional, are heated in the winter to prevent them from gathering ice.

Designed by famed architect Frank Gehry, the Walt Disney Concert Hall opened in downtown Los Angeles in 2003. Named in honor of the legendary animation filmmaker, the Walt Disney Concert Hall is the home of the Los Angeles Philharmonic. The building has a striking stainless steel exterior and a hardwood-paneled interior, ideal for the acoustic needs of a classical orchestra.

St. Louis’ Gateway Arch was completed in 1965 by famed Finnish-American architect Eero Saarinen, who based the design on a catenary curve (the shape made by a free-hanging chain when held at both ends). At 630 feet high — and as wide as it is tall — the Gateway Arch is the tallest monument in the United States. The arch honors Thomas Jefferson, Lewis & Clark, Dred Scott, and other historical figures.

Designed in the early 1900s by Robert Reamer and built of local logs and stone, the Old Faithful Inn is the most popular lodging facility in Yellowstone National Park. The inn has a towering lobby with a massive stone fireplace and rises up six stories. The hotel has more than 300 rooms and was designated a National Historic Landmark in 1987.

Located in Asheville, North Carolina, the Biltmore is the largest privately-owned house in the United States. The massive mansion was built for George Washington Vanderbilt II in the late 1800s, and it boasts more than 178,000 square feet of floor space. The Biltmore has 250 rooms, including a library with 10,000 volumes, a banquet hall with a 70-foot ceiling, 65 fireplaces, an indoor pool, and a bowling alley.

New York City's Chrysler Building is often cited as the epitome of Art Deco architecture. Designed by William Van Alen and finished in 1930, the shining steel tower exemplifies the Art Deco movement's clean, sleek, and luxurious characteristics. When it was finished, the Chrysler Building was briefly the tallest structure in the world before the Empire State Building surpassed it less than a year later.

In 2019, eight buildings designed by famed American architect Frank Lloyd Wright were collectively named a UNESCO World Heritage Site. Among them are Taliesen in Spring Green, Wisconsin; the Robie House in Chicago, Illinois; and Fallingwater in Mill Run, Pennsylvania. All three are considered eminent examples of American architecture for their groundbreaking techniques and incorporation of the environment around them.

With a name meaning "Little Mountain," Monticello was the primary home of Thomas Jefferson from 1770 until his death in 1826. In addition to authoring the Declaration of Independence and serving as the third U.S. President, Jefferson was also an accomplished architect, and designed the home outside of Charlottesville, Virginia, himself.

Just two years after the opening of the Empire State Building, the tower was featured in the climax of the 1933 movie "King Kong,” when Kong climbs what was then the world's tallest building. The iconic scene boosted the already high profile of the Empire State Building and helped push the art deco structure even further into the pantheon of U.S. architecture.

In 1969, Sears Roebuck and Company decided it needed a central office space for its 350,000 employees, so they commissioned a 1,730-foot tower in the heart of Chicago. After it was completed in 1973, Sears Tower was the tallest building in the world for 25 years. In 2009, the building was renamed Willis Tower after Willis Group Holdings, an insurance brokerage.

Built in 1962 for that year's World's Fair, this iconic 605-foot observation tower was once the tallest tower in Seattle (and in all of Washington). Since then, eight other buildings have passed it in height, including the 933-foot Columbia Center, which is currently the tallest building in Seattle’s skyline.
