1. It’s The Smallest National Park
Let’s begin our interesting list of Gateway Park National Park Facts with the one which often attracts the most attention.
At a mere 91 acres, Gateway Arch National Park is the smallest national park in America. It doesn’t even have a natural area.
So why, you might ask, is it a national park? That’s a good question. Unfortunately, it’s not one that I can safely answer other to say that these decision are sometimes made on the basis of political considerations and having powerful friends in Congress never hurts whether your state’s park is deserving of national park status or not.

2. The Park Was Originally Inspired By Jefferson’s Vision
If you’re interested in origin stories then one of the most interesting Gateway Arch National Park Facts is that St. Louis was the capitol of the Louisiana Territory from 1812 until Missouri gained statehood in 1821.
It was the vision of America’s third president, Thomas Jefferson, that Missouri should serve as the “Gateway to the West.”
That vision is symbolized today by the iconic Gateway Arch. So, in fact, you could say that Jefferson’s Vision inspired both the arch and the park.

3. The Gateway Arch Represents The Jumping-Off Point Of America’s Age Of Westward Exploration
For me, one of the most intriguing of the Gateway Arch National Park Facts involves the fact that the arch represents the jumping-off point of 19th century America’s age of westward exploration.
From the newly acquired Louisiana Purchase to Lewis & Clark’s Corps of Discovery and the subsequent westward expansion of the North American continent, it is the doorway to America’s “manifest destiny.”
Manifest Destiny, a phrase coined in 1845, is the idea that the United States is destined—by God, its advocates believed—to expand its dominion and spread democracy and capitalism across the entire North American continent. It’s an interesting idea and one which helped to drive America’s quest to go from “sea to shining sea.”
Symbolically speaking, a journey through this fabled arch signifies our nation’s grand mission to occupy all of the land from sea to shining sea.

Now here’s another one of those amazing Gateway Arch National Park Facts. Before becoming a flagship national park in 2018, the Gateway Arch Visitor Center underwent a $380 million dollar renovation. That’s right! $380 million dollars!
Totaling more than 150,000 square feet, it’s accessed by a semi-circular entryway that is accentuated by the site’s curving geometry. The lobby is actually dug into a berm and organized around a circle of water. An artistic masterpiece!
You’ll be hard pressed to find a more magnificent visitor center at any other national park in America.

6. A Finnish-American Architect Won A Nationwide Competition To Design The Famous Arch
Just when you thought we couldn’t come up with any more unbelievable Gateway Arch National Park Facts we’ve come up with another one.
A nationwide design competition was launched in 1948 to determine what shape the Memorial would take. Architect Eero Saarinen’s design won and, in 1963, construction began on a stainless steel arch.
Saarinen was a Finnish-American architect and industrial designer noted for his wide-ranging array of designs for buildings and monuments.
Among his other designs were the General Motors Technical Center in Michigan and Washington Dulles International Airport outside of Washington D.C.
Saarinen’s motivation was to honor Thomas Jefferson, but to also create a structure “which would have lasting significance and would be a landmark of our time.”
It was completed two years later in 1965. Today, it stands as a symbol of national identity and an example of mid-century modern design.

As a retired history teacher I am always fascinated by the stories of the people behind these wonderful projects. One of my favorite of the Gateway Arch National Parks Facts has to do with just such a person.
Luther Ely Smith was a 19th century St. Louis lawyer and civic booster who first proposed a riverfront memorial for President Thomas Jefferson. It was his efforts which led to the creation of the Gateway Arch.
It is therefore fitting and appropriate that the park which bears his name should welcome visitors to the Jefferson National Expansion Memorial and Gateway Arch National Park.
