San Jacinto Battleground State Historic Site

San Jacinto Battleground State Historic Site is a historic military battlefield in Harris County, Texas, with a tall tower and open grasslands. The grounds spread across flat coastal terrain near a shipping channel and include walking paths and interpretive panels.

Texan militia fought Mexican troops here in 1836 and won within minutes. This military victory led to the founding of the Republic of Texas.

The name comes from a Spanish term for a local plant that grew along the coast. Visitors today see memorial stones and flags that recall the conflict between Texan settlers and Mexican troops.

The grounds are open daily from 9 AM to 6 PM, and visitors can explore the park and outdoor trails at no charge. The tower and museum require an admission fee, and parking is available near the entrance.

Groundwater movements have shifted the shoreline, and part of the original combat ground now lies underwater. This change shows how the coastal landscape has evolved over time.
