Most structures exist to serve a functional purpose, but some define the area in which they stand. Take the Eiffel Tower, for example. One look at the towering wrought-iron structure and you know exactly what city you're seeing.
At least one instantly recognizable building or otherwise touristy location stands proud in each U.S. state. Here's a roundup of the most distinguishable structures in each state and what it costs you to visit these popular tourist attractions.
Alabama: The Alabama State Capitol
Completed in 1851, the Alabama State Capitol is a National Historic Landmark that stands proud in Montgomery. After all these years, the Capitol building is still functional, used by the governor and executive branch officers.
Built to replace the original Capitol building that burned down in 1849, the initial structure cost $60,000. Since then, several rounds of updates have been made, including $150,000 to build a south wing in 1905 and $100,000 for a north wing in 1911. The building underwent a major restoration in 1992.
Alaska: The Trans Alaska Pipeline System
Built in 1977, the Trans Alaska Pipeline System was the largest privately funded construction project at the time, with a price tag of $8 billion. Totaling 800 miles in length, it's one of the most extensive pipeline systems in the world. More than 124,000 heat pipes work together to transfer ground heat into the air, making sure the soil is stable and able to support the pipeline.
Arizona: The Grand Canyon Skywalk
The Grand Canyon Skywalk is a glass platform that allows you to look 4,000 feet into one of the world's greatest natural wonders. The 10-foot-wide bridge projects 70 feet over the Canyon rim and is strong enough to support the weight of 70 747 passenger jets.
Located on Grand Canyon West, the $30 million structure was built by the Hualapai Tribe in 2007. If you want to experience this wonder for yourself, tickets start at $82.37.
Arkansas: Little Rock Central School
Built in 1927 for $1.5 million, Little Rock Central School is a National Historic Site. Made famous by the Little Rock Nine — nine African American students who exercised their right to attend the then-segregated school on Sept. 25, 1957 — this educational institution is rich with history.
Still functioning, approximately 2,500 students walk through its halls on a daily basis. Free tours of the high school are available with a reservation.
California: The Hollywood Sign
It's one of the most famous landmarks in the world, but the original Hollywood Sign only cost $21,000 to build. Constructed in 1923, it was initially an advertisement for Hollywoodland, a ritzy real estate development. The City of Los Angeles took ownership of it in the mid-1940s, removing the "land" portion of the sign for roughly $4,000.
Declared a historical landmark in 1973, the sign was completely rebuilt for $250,000 in 1978. To bankroll the rebuild, community leaders and celebrities like Hugh Hefner threw fundraisers, while Alice Cooper, Andy Williams and Gene Autry sponsored individual letters for $27,500 each.
Colorado: Red Rocks Amphitheatre
Located 15 miles west of Denver, Red Rocks Amphitheatre is more than just a gorgeous concert venue. The National Historic Landmark is 6,450 feet above sea level and surrounded by 738 acres of wildlife and geological sensations.
Owned by the City of Denver since 1927, Red Rocks was purchased for $54,133. In 2008, the site's redwood benches were replaced, and the old pieces were auctioned off for more than $250 each. The cost to rent Red Rocks starts at $7,500, and the fee for supplemental expenses including lights, sound and security can be more than $100,000.
Connecticut: Harkness Tower
Yale University's Harkness Tower stands tall over the Ivy League campus. Donated in 1917 by Anna M. Harkness in memory of her Yale alumnus son, she followed this gift with the tower's original 10-bell chime in 1921. The 200-foot-high tower cost $2.5 million to build.
In 1966, Floren S. Marcy Grofut gifted the additional 44 bells in memory of her parents. The university spent more than $1 million renovating Harkness Tower in 1982.
Delaware: Grand Opera House
The lavish, stunningly beautiful Grand Opera House in Wilmington has been standing proud since 1871. Built as a Grand Lodge of the Masons, construction cost just $100,000. Since then, the venue has hosted thousands of luminaries, including John Philip Sousa.
Restored in 1973, the Grand hosts more than 300 events per year, welcoming upwards of 120,000 people annually.
Florida: Raymond James Stadium
Built in 1998 for a whopping $168.5 million, Raymond James Stadium is home to the Tampa Bay Buccaneers. Funded entirely with public money, a 30-year, half-cent sales tax was imposed on Tampa's Hillsborough County to build the 65,908-seat stadium. While the cost to build the stadium was high, the cost to see the Buccaneers play is highly affordable.
A two-time Super Bowl host, it's also the site of the annual New Year's Day Outback Bowl. The initial phase of a more than $140 million stadium overhaul was completed in 2016.
Georgia: Centennial Olympic Park
Centennial Olympic Park was built in 1996 when Atlanta hosted the Summer Olympics. Previously a cluster of dilapidated warehouses, the 21-acre park was built with $75 million in private funds. Part of the funding came from the sale of thousands of bricks purchased by individuals for $35 each, each of which is engraved with a brief message and laid throughout the park.
The park is home to many popular attractions, including the College Football Hall of Fame and the World of Coca-Cola. It also features hotels, nightlife, restaurants and residential development.
Hawaii: Aloha Tower
Located on Pier 9, the 10-story Aloha Tower has been a focal point for ships arriving in Honolulu since 1926. The iconic tower took five years to build, with a price tag of $160,000 — which equates to more than $2 million today.
The tallest building in Hawaii for roughly 40 years, the Aloha Tower was painted in camouflage after the 1941 Pearl Harbor attack, so it would be difficult for enemies to see at night. Largely considered one of the state's most endearing landmarks, the tower is on the National Register of Historic Places.

Iowa City's only National Historic Landmark has been a museum since 1976. Located on the University of Iowa Pentacrest campus, the school used it for classes and more prior to transforming it into a museum.
Kansas: The Kansas State Capitol
Situated on a 20-acre tract in downtown Topeka, the Kansas State Capitol is recognizable by its bronze Ad Astra statue perched atop its copper dome. The building took 37 years to construct, partially because the original east wing cornerstone crumbled just months after it was laid due to a harsh winter.
The building was completed in March 1903 for a cost of $3,200,588.92. The Kansas City Historical Society provides historic tours of the building Monday through Friday. Reservations are strongly encouraged.

Massachusetts: Fenway Park
Home of the Boston Red Socks, Fenway Park opened its gates in 1912. Built for just $650,000, team owners considered building a new ballpark in recent years but opted to preserve the historic 37,731-seat venue instead.
Since deciding to keep the stadium in play, improvements totaling approximately $285 million have been budgeted, including the addition of three new high definition video boards and scoring systems back in 2011.
Michigan: Fisher Building
More than just a skyscraper, the Fisher Building is an Art Deco masterpiece that has been towering high above Detroit since 1928.

The Fisher Building itself cost roughly $9 million, with 25 percent allocated to the building's art and décor.
The lobby is adorned with elaborate frescoes, which cost more than $20,000 to create — roughly $265,000 today.

Built for $12,000 in 1848, the 64-foot Biloxi Lighthouse was one of the first cast-iron lighthouses in the South. Run by civilians until 1939, the lighthouse was notably operated by several female lightkeepers. The Coast Guard took control in 1939, and after being declared surplus property, it was deeded to the City of Biloxi in 1968.
In 2005, Hurricane Katrina caused extensive damage to the Biloxi Lighthouse. It reopened in 2010 following a 14-month, $400,000 restoration.

Montana: Moss Mansion
The Moss Mansion was built in 1903, but it's still one of the grandest homes in Billings. It cost $105,000 to build, which doesn't seem like much now, but the average home price in the area at the time was just $3,000.
Designed by Henry Janeway Hardenberg — the New York-based architect behind the original Waldorf Astoria and Plaza Hotels — the mansion is listed on the National Register of Historic Places. The home opens its doors to visitors year-round.
Designed to pay homage to Stonehenge in England, Carhenge is a unique car sculpture by artist Jim Reinders. One of the weirdest roadside attractions in America, Carhenge consists of 39 vehicles placed in the same proportions as Stonehenge. This unique work has been standing tall in Alliance since 1987.
The site almost sold for $300,000 in 2011, but the deal didn't happen because the buyer wanted to move the sculpture to another site. Now owned by the city, site maintenance costs approximately $39,000 annually.
