Did you know Jackson, Mississippi, is named after the 7th U.S. President, Andrew Jackson? It is one of the four state capitals named after American presidents —the other three are Jefferson City (Missouri), Lincoln (Nebraska), and Madison (Wisconsin).

Jackson is the only U.S. capital built on top of an extinct volcano. Interestingly, during the Civil War, the city was burned by Union troops, giving it the nickname "Chimneyville". In addition, Jackson is best known for being the center of the civil rights movement during the 1950s and 1960s.

In 1610, Spanish settlers established Santa Fe as the capital of New Mexico, making it the oldest state capital in the country. But that's not the only peculiarity of this quaint city with a temperate climate and a unique historical and cultural richness. At 7,000 feet above sea level, Santa Fe is also the highest U.S. capital.

Known for its spectacular beaches and rich cultural heritage, Honolulu is the only state capital not on the North American mainland. Considered the birthplace of modern surfing, it also has the highest average annual temperature of any U.S. state capital.

But those aren't the only interesting facts about Hawaii's capital. Here are a few equally (or more) crazy ones: it hosts the only royal palace in the United States (Iolani Palace), the island is made up of volcanic soil, and it houses the world's largest open-air shopping mall (Ala Moana Center).

Annapolis is a historic city on the shores of the Chesapeake Bay, known for its colonial architecture, nautical tradition, and academic value. But did you know it is also the smallest U.S. capital by land size? Just 6.7 square miles!

Annapolis was also one of the nine capitals the United States has had throughout its history. For nine months during the Revolutionary War, Maryland's current state capital served as the seat of the Confederation Congress.

If you thought Juneau, Alaska, had the lowest average winter temperature of all state capitals, think again! It's actually Bismarck, North Dakota, where the coldest temperature ever recorded was -45°F. Imagine that!

Bismarck was founded in 1872 on the banks of the Missouri River. The city was named after Otto von Bismarck, the chancellor of Germany, to attract German investors. Another fun fact? In 1930, Bismarck and Fargo had a dispute, known as the "Capitol Tower War," over which city should be the state capital.

Did you know that the original name of West Virginia's capital was Charles Town in honor of the father of Colonel George Clendenin, one of the first settlers?

Founded in 1635, Connecticut's capital is one of the oldest cities in the U.S. Hartford is known for being a key cultural center in New England. It was the home of writer Mark Twain and is home to historic sites such as the State Capitol, the Harriet Beecher Stowe House, and Bushnell Park, the oldest public park in the country.

Hartford is also called the "insurance capital of the world" due to the presence of major insurance companies. But the city's most curious fact is that it was where Teddy Roosevelt, aboard the Columbia Electric Victoria Phaeton, took the first presidential automobile ride in history!

Pennsylvania's capital city is best known for its role in the Civil War and the Underground Railroad. Located on the banks of the Susquehanna River, Harrisburg has been an important center of transportation and commerce. Today, it is known for its historic architecture, museums, and special events.

Harrisburg is also home to the longest stone arch bridge in the world, the Rockville Bridge, built in 1902. Oh, and in 1979, it came close to a nuclear disaster due to the accident at the Three Mile Island plant, the worst in U.S. history —but that's a longer story for another article!

Located at the southern tip of Puget Bay, Washington's state capital is known for its natural beauty and vibrant culture. But did you know Olympia is the northernmost state capital in the contiguous U.S.?

Oh, and it's also a great place to try some of the best craft beer in the country!

Utah's state capital is popular for being one of the best places to ski in the United States. But that's not all! Salt Lake City is also the only state capital with three words in its name. Have you ever thought about that?

It has the largest Mormon population in the country and is the world headquarters of the Church of Jesus Christ of Latter-day Saints. Another fun fact? Salt Lake City is home to more plastic surgeons per capita than any other state capital!

Named after the French city of the same name, Montpelier is the least populated state capital, with a population of just 7,900. Probably for that reason, Vermont's capital prides itself on its small local businesses: it is the only state capital that doesn't have a McDonald's or a Starbucks. Could you live without these fast food chains? It doesn't have a Walmart store either!

Topeka, Kansas’s state capital, has several interesting tidbits. For example, did you know its name, of Native American origin, means "a good place to dig potatoes"? Interesting, don’t you think?

In 2010, Topeka temporarily changed its name to "Google, Kansas" to attract the attention of the internet giant and become the capital city of fiber optics. Frivolous facts aside, Topeka was also very important in the history of the civil rights movement.
