The "Engine of Life" display, which cost $40,000 when it was built in 1953, was only scheduled to be available to the public for six months. However, visitors continue to come from around the world who want to see this amazing piece of art.
The total cost of the Franklin Institute when it opened its doors to the public was $4 million ($20 million in today's dollars). The original intent was to raise funds to endow a chair in electrical engineering but that goal was never reached. Instead, the institute has maintained its status as an educational nonprofit organization since its founding in 1824.
Franklin invented many things including the first electric light, the bifocal lens, and the phonograph. But he's most famous for his contributions to electricity and science more generally. He is considered the father of applied science because of his work in electricity and magnetism.
He had a very modest upbringing and showed an early interest in science. When he was only 16 years old, he wrote a letter to Benjamin Franklin asking for advice on how to pursue a career in science. Franklin responded by suggesting that he study mathematics and physics rather than medicine or law because they were more useful skills.
When the components came, the building alone cost $500,000, which was a great figure at the time. The total cost of construction is estimated to be around $3 million.
Hammond Castle is one of the most expensive buildings in America. It took builders about five years to complete its construction. The castle has 48 rooms and seven fireplaces.
The castle's main structure is an eight-story stone wall with a wooden interior. The walls are nearly two feet thick and the building weighs almost 20,000 pounds. Inside the castle, guests can enjoy a magnificent banquet room with a floor made of Italian marble. There are also three libraries, a music room, and a ballroom with a ceiling made of glass tiles.
The castle grounds include a deer park, a golf course, a swimming pool, a tennis court, and a clock tower. In addition, there are more than 10,000 trees on the property.
Hammond Castle was built by Arthur Hammond, who was born in Ireland but moved to Chicago when he was young. He started out as a stockbroker but later on became a wealthy businessman who owned banks and railroads. He bought land in Illinois and Indiana for future development projects.
More than 2,000 people worked on the project at its peak, and it took around five million man-hours to finish. The structure, which took three years to finish and weighs 46,000 tons, utilized enough steel to make 33,000 automobiles. It is estimated that it has been built over 100 times since its completion in 1964.
The Hancock Tower is 112 stories high and has 925 apartments. Its construction cost $77 million at the time it was completed. At the beginning of 2012, the tower had not yet reached its maximum life expectancy and was expected to remain in use for several more decades.
It is believed that this kind of construction is never done again because it requires such a large amount of labor and material resources. However, buildings of similar scale are still being constructed today, although they are not as expensive as the Hancock Tower.
In addition to being a landmark in Chicago, the Hancock Tower is also famous for being the first skyscraper to have an observatory on each of its floors. These public viewing galleries were actually added after the building was complete but before it was sold to its current owners. They contain offices and storage space today but originally planned to be living quarters with views of downtown Chicago.
The building's design was created by architect William Meyer Van Der Ryn van Santvoord and he also designed another famous Chicago skyscraper, the John Hancock Center.
DESIGN AND CONSTRUCTION HIGHLIGHTS More than 2,000 people worked on the project at its peak, and it took around five million man-hours to finish. It is estimated that well over 100,000 gallons of concrete were used in its fabrication.

It was built by a team of architects from several countries including Henry Cobb of Boston, Edward Bennett of Chicago, and Albert Kahn of Milwaukee, who had never before collaborated on a project. The team's only requirement for their work was that it had to be "different." They succeeded in designing a building that was innovative in its use of glass walls, aluminum panels, and open floors. This allowed much of the interior to be seen from the outside, giving the building a bright and airy appearance.
The construction period spanned from 1951 to 1953. However, due to complications with the financing plan, it wasn't until nearly two years after they started that the first piece of the building material was delivered to the site.
The facility opened to the public in January after nine years of development at a cost of $4.5 million. The dome was built two years later for $15 million.
The state capitol was built with money from a tax on tobacco that was passed by voters in November 1992. The measure provided $150 million over eight years for construction of "economic development" projects in Minnesota. (The other half came from an increase in the sales tax.)
The capitol building campaign received more than $100 million in public funding. The remaining funds came from private sources and bond issues. The first floor consists primarily of legislative offices, while the second floor is home to the governor's office and some administrative facilities.
The total cost of the capitol building project was $155 million. This includes $14.8 million for site work, buildings, grounds, and infrastructure improvements related to the capitol project. An additional $10 million was spent on research and design services for the project.
The state legislature approved a resolution on March 25, 1993, authorizing the sale of $50 million in bonds to pay for part of the capitol project.
