The first major entrance for Yellowstone was at the north boundary. Robert Reamer, a famous architect in Yellowstone, designed the immense stone arch for coaches to travel through on their way into the park. At the time of the arch's construction, President Theodore Roosevelt was visiting the park. He consequently placed the cornerstone for the arch, which then took his name. The top of the Roosevelt Arch is inscribed with "For the benefit and enjoyment of the people," which is from the Organic Act of 1916.
