Duval County, Texas

Duval County is located in South Texas, about an hour west of Corpus Christi, and has a history filled with colorful stories, political controversies, and long-running land disputes. Its past has played an important role in shaping the county’s unique identity.

San Diego serves as the county seat—not the California city, but a distinctly Texan community with deep local roots. Hispanic heritage is an important part of everyday life here, reflected in the culture, traditions, and languages spoken throughout the county.

Ranching remains a longstanding way of life, while oil and gas production continue to contribute to the local economy. More recently, wind energy has become another visible part of the landscape.
