Fort Jesup, located in western Louisiana, was constructed in the early 19th century in order to provide protection on the western edge of the United States. Throughout its military life, the fort presided over the furthest western reaches of the United States of America, which terminated at the Sabine river, which forms the modern-day border between Texas and Louisiana. In addition to providing protection, the garrison provided many other crucial functions, such as road construction, surveying, and treaty negotiation. The fort was designated a national historic landmark in 1961.
