San Antonio Missions National Historic Park
A 12-mile route through the San Antonio area highlights the 18th-century Spanish missions that once served as the focal points of their communities. The most famous of these is the Alamo, which was defended by Texans against a Mexican army as part of the state's war of independence. Markers, statues, a museum and tours highlight the site, which is a national landmark. Mission Espada, San Juan Capistrano and Concepcion also make up the string of national monuments.

Chamizal National Memorial
The Chamizal National Memorial commemorates the historic 1963 treaty that permanently set a long-disputed border between the United States and Mexico. The border had been set in 1848 as the Rio Grande River, but the river had moved south over time, leading to the dispute. The site hosts numerous cultural activities during the year and houses a museum.
