Gateway to the West - St Louis, MO
The "Gateway Arch" or "St Louis Arch" is located in the Jefferson National Expansion Memorial near Busch Stadium along the Mississippi River in St Louis, MO.
It's the tallest man-made national monument in the United States. If you are in St Louis or even just driving through, be sure to stop off and see this.
There are a lot of composition angles to try. There is a great deal of space near and around the arch itself to get some great shots of the structure.
At 630 feet tall, this is also the tallest accessible building in the entire state of Missouri.
