Gateway Arch National Park

Gateway Arch National Park Overview

Formally known as the Jefferson National Expansion Memorial, Gateway Arch National Park was established as such in early 2018. At only 91 acres, it is the smallest park in the National Park Service and its new designation was not necessarily highly received by the public or NPS. Although it is not the only park located in a busy downtown, Gateway Arch is the only national park that centers around a man-made structure. There are no true trails or hikes in Gateway National Park that parks such as Yosemite or the Grand Canyon attract visitors from all over the world. Still, the historical significance of the park cannot be dismissed. The Arch symbolizes the starting point of the Lewis and Clark expedition while the Old Courthouse was home to several famous American trials.
