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, set to Mexican time, thirty-six minutes ahead; the timepiece has become a tourist attraction.
The fort was built. It was built in sections, started in 1830 by don Jesus Treviño, continued by don Blas Maria Uribe in 1850 and final construction and/or modifications by don Jose D. Uribe.

San Ygnacio is the last South Texas community to exhibit such a large collection of the once-numerous sandstone structures built in the middle and late nineteenth century
The San Ygnacio, Texas historic district had thirty-six stone buildings. The stones come from nearby rock formations. The exterior is finished with lime mixed with liquid squeezed from cactuses. Many have been refurbished as the one shown on the right.
"This historic structure which served as a customs house from 1800 to 1869 is dedicated in honor and recognition of two centuries of service by men and women of the U.S. Customs Service. This, contribution and sacrifice, has played a significant role in the development of the United States of America and the protection of its citizens."
