El Camino Real de Tierra Adentro is recognized throughout the United States of America and Los Estados Unidos de Mexico as a timeless route of trade and cultural exchange and interaction among Spaniards and other Europeans, American Indians, Mexicans, and Americans, which shaped individual lives and communities and affected settlement and development in the greater Southwest. Recognition of this route as an international historic trail will commemorate a shared cultural heritage and contribute in a meaningful way to eliminating cultural barriers and enriching the lives of people along El Camino Real de Tierra Adentro.

Four Spanish frontier missions, part of a colonization system that stretched across the Spanish Southwest in the 17th, 18th, 19th centuries, are preserved here. They include Missions San Jose, San Juan, Espada, and Concepcion. The park, containing many cultural sites along with some natural areas, was established in 1978. The park covers about 819 acres.

The Chamizal Convention was a milestone in diplomatic relations between Mexico and the United States in 1963. Chamizal National Memorial in El Paso was established to commemorate this treaty which resulted in the peaceful settlement of a century-long boundary dispute between the neighboring countries. Far more than mere acreage, Chamizal is an idea, a dynamic process, dedicated to furthering the spirit of understanding and goodwill between two nations that share one border. Utilizing the visual, literary and performing arts as a medium of interchange, Chamizal serves as an open door to help people better understand not only other cultures, but their own cultural roots as well.

Set in the rugged beauty of the Davis Mountains of west Texas, Fort Davis is one of America's best surviving examples of an Indian Wars' frontier military post in the Southwest. From 1854 to 1891, Fort Davis was strategically located to protect emigrants, mail coaches, and freight wagons on the Trans-Pecos portion of the San Antonio-El Paso Road and the Chihuahua Trail, and to control activities on the southern stem of the Great Comanche War Trail and Mescalero Apache war trails. Fort Davis is important in understanding the presence of African Americans in the West and in the frontier military because the 24th and 25th U.S. Infantry and the 9th and 10th U.S. Cavalry, all-black regiments established after the Civil War, were stationed at the post. Today, twenty-four roofed buildings and over 100 ruins and foundations are part of Fort Davis National Historic Site. Five of the historic buildings have been refurnished to the 1880s, making it easy for visitors to envision themselves being at the fort at the height of its development.

On May 8, 1846 troops of the United States and Mexico clashed on the prairie of Palo Alto in the first battle of a two-year war. Signed into law in June 1992, Palo Alto Battlefield National Historic Site located near Brownsville preserves the 3,400-acre scene of this clash between nations and informs visitors about its national and international importance. As the only unit of the National Park Service with a primary focus on the U.S.-Mexican War, Palo Alto Battlefield also interprets the entire conflict--including the details of its origins and the broad range of consequences. In an effort to turn a scene of conflict into a place of bi-national exchange and understanding, all research and interpretation conducted by the park reflects perspectives of both the United States and Mexico.
