The arch, designed by the renowned Yellowstone architect Robert Reamer, measures 50 feet tall, with two towers each 12 feet broad at their base. The hole provides a space 30 feet high by 25 feet wide, more than enough area for horse-drawn carriages to pass through, as it was originally planned to accomplish. However, due to budget constraints, only one carriage can fit through at a time.
In addition to its aesthetic value, the arch serves an important function at keeping animals out of the developed areas of the park. Any animal that tries to climb over the fence will run into this obstacle first thing in the morning and again around sunset, when most visitors are returning from their tours.
As you might expect given its name, Yellowstone National Park is located in Wyoming, USA. It covers 828 square miles and has three geysers that reach temperatures up to 400 degrees Fahrenheit. It's been called the "heartbeat of America" because it shows many signs of life after almost 100 years without any natural disasters.
Yellowstone received its name from its famous geysers, which used to be covered in dense forests but now mostly lie barren because of increased tourism. In fact, nearly 90% of the original forest has been removed and most of the rest is threatened.
The arch is 164 feet (50 metres) high and 148 feet (45 metres) broad, designed by Jean-Francois-Therese Chalgrin. It is located in a circular plaza from which 12 great avenues extend, creating a star (etoile), thus the name Arch of Triumph of the Star. The arch's construction began on August 15, 1806, Napoleon's birthday. It was completed four years later.
In addition to being a monument to the glory of France, the arch serves as a place of commemoration for those who died during Napoleon's wars. Over 70,000 men were killed in battle or died while serving in his army. They are buried in more than 70 military cemeteries that surround Paris in areas now called Invalides, Montmartre, Père Lachaise, and Saint-Denis.
The arch is also used as a location for many films and television shows, including: "I Love Paris" (2006 film) starring Gerard Depardieu, Céline DION, and Daniel Auteuil; "Mission: Impossible - Ghost Protocol" (2011 film) starring Tom Cruise; and the "Harry Potter" series (2001-2011) with Daniel Radcliffe. The plaza beneath the arch is also used as a set for various commercials throughout the year.
The arch is open daily from 9 a.m. to 11 p.m.; entry is free. There are information panels in several languages that explain the history of the site.
It is the highest arch in the world. The arch is 630 feet tall, making it the largest man-made landmark in the United States and the tallest accessible building in Missouri. 2. The arch is as tall as it is broad. The base of the arch is 630 feet wide. The top of the arch is 90 feet above ground level.
3. It took more than 10,000 tons of steel and almost $200 million to build the arch. The main pieces of the arch were built in Jefferson City and St. Louis, and then it was assembled on site in 1965-68. The total cost was $14.5 million at that time.
4. The arch stands on a granite foundation that covers an entire city block in downtown St. Louis. The entire structure does not weigh much - only about 14,000 pounds.
5. It takes eight people one hour to climb up the stairs inside the arch.
6. It takes about 45 minutes to walk around the arch perimeter.
7. You can reach the top of the arch by taking either of the elevators located on either side of the tower. Each elevator carries up four people at a time. They travel at a rate of nearly 20 stories per minute, which makes the trip up feel like half as long.
The arch is 630 feet tall and 630 feet broad, despite its appearance. Because you are not constantly staring at the arch straight on, you get the impression that it is considerably higher than it is broad.
The arch was built as a monument to America's history with its roads and bridges. It is made of limestone from Missouri and has more than 7 million cubic yards of stone in it. The total cost was $140 million at the time it was built.
You can walk inside the arch but it is only open during special events or holidays. Otherwise, you have to make do with looking at it from outside the fence line!
It took about 6 months to build the arch. The main idea behind its design was simplicity so that everyone could understand it was a bridge even if they were not physics students. The arch itself is made of two parts, both made of steel: the truss and the legs. The middle part of the truss is hollow so that more traffic can pass through it. This is where all the magic happens - the wind blows across the top of the truss causing it to bend which makes the legs lift up and hold the arch up. There are also cables attached to the bottom of each leg which give it extra support when the arch is being used as a bridge.
By the Numbers: The Gateway Arch The Gateway Arch is the highest landmark in the United States, at 630 feet tall. It is as long as it is wide. Its shadow covers 1.8 million square feet, which is the same size as Chicago's population. Its peak to peak span is 90 feet. It took more than 30,000 bolts to build the arch. Benjamin Franklin designed the original key for American Independence Hall now on display in Philadelphia. He also designed the first U.S. flag with 13 stripes and a big star-spangled banner in 1777.
The Jefferson Memorial is the second tallest monument at 555 feet high. It was built between 1941 and 1943. The memorial is made of white marble from Vermont. On its front is an image of Thomas Jefferson, his hands folded in prayer. His face is illuminated by a bright light coming from inside the statue.
The Lincoln Memorial is the third highest at 535 feet. It was dedicated on October 31, 1922. The memorial is made of limestone from Indiana and Maryland. On its front is an image of Abraham Lincoln, standing with his arms outstretched. He is looking up toward the sky with hope in his eyes.
The Washington Monument is the fourth highest at 476 feet. It was built from 1825 to 1851.
