Palo Alto Battlefield National Historic Site


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 (NHS) 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 NHS 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. The park is open daily, 8 a.m. to 5 p.m. year-round. Closed Thanksgiving Day, December 25, and January 1. The park trail and battlefield overlook close at 4:30 p.m. The park visitor center offers an orientation video and exhibits on the battle of Palo Alto and the U.S.-Mexican War. Visitors may also browse a book sales area of some 100 titles and obtain pamphlets about the park and related sites.
