San Ygnacio
San Ygnacio (Ignacio), the oldest town in Zapata County, is on the Rio Grande and U.S. Highway 83, thirty miles south of Laredo and fourteen miles northwest of Zapata. It was settled in 1830 by former residents of Revilla (now Nuevo Guerrero, Tamaulipas) under the leadership of Jesús Treviño. The site was in the southwest corner of the original Hacienda de Dolores, a grant made in 1750 by Col. José de Escandón to José Vázquez Borrego, and was named for the patron saint of Guerrero, Saint Ignatius Loyola. In 1830 Treviño built a sandstone home, known as Fort Treviño, 100 by 140 feet. José Villarreal placed a sundial at the home in 1851; the timepiece has become a tourist attraction.
