Palo Alto Battlefield National Historical Park Park

Website: https://www.nps.gov/paal/index.htm

Palo Alto Battlefield National Historical Park preserves the site of the first major U.S. engagement of the Mexican-American War, located near Brownsville in southern Texas and interpreted by the National Park Service. The park focuses on the battles fought there in May 1846 and their local significance.

The park presents the open battlefield landscape with short interpretive trails and outdoor waysides. Visitors can see the terrain where troop formations engaged across marsh and prairie and view museum exhibits that explain troop movements and the campaign. The nearby Resaca de la Palma battlefield is interpreted as part of the same unit and is connected in the park narrative.

U.S. forces under General Zachary Taylor fought Mexican forces commanded by General Mariano Arista on May 8, 1846 at Palo Alto, followed by a second engagement at Resaca de la Palma on May 9, 1846. Over time the sites have been preserved and interpreted by federal and local efforts; the area is managed as a National Park Service unit to protect battlefield topography and tell the history of the campaign.

The park sits in Cameron County in the Rio Grande Valley, south Texas, near the city of Brownsville and close to the U.S.-Mexico border. The landscape is low-lying coastal plain characterized by prairie and seasonal wetlands.

• Historic battles: The two consecutive battles of May 8 and 9, 1846 are interpreted on-site and are the opening large engagements of the Mexican-American War.
• Visiting notes: The site lies in the Rio Grande Valley near Brownsville and can be visited year-round; summer temperatures are very high so mornings are best for outdoor walking.
