Casa Blanca was two miles southwest of Sandia and twenty miles northeast of Alice in extreme northeastern Jim Wells County. The Casa Blanca or White House was part of a settlement established at the site around 1754 by Tomás Sánchez de la Barrera y Gallardo, captain of Laredo, who was ordered to find a suitable site for a new settlement. After surveying the country Sánchez selected a site on the banks of Peñitas Creek. A settlement was established there, and the White House was constructed of caliche blocks known as ciares. The house was built in the shape of a square with a courtyard in the center; the well in the courtyard also served as a the end of a tunnel out of the building. Toward the end of the eighteenth century the house was used as a mission.

The Spanish crown granted the land to Juan José de la Garza Montemayor and his sons Agustín, Perfecto, and Manuel on April 2, 1807. They used the Casa Blanca as a ranchhouse. According to records the land was occupied by their heirs until 1852. However, local legend has it that the Montemayor family was driven away by a band of outlaws, who in turn were driven out by hostile Indians. Subsequently various families occupied the house and the surrounding area, and a post office operated at the site from 1860 to 1866. The area continued to be inhabited by several families, and in 1893 the post office was reactivated. In 1896 the land was purchased by John L. Wade. Because Casa Blanca was already established as a stopping point Wade established Wade City adjacent to it, platting streets and setting aside land for stores and churches. In 1896 Casa Blanca-Wade City had a combined estimated population of 150, a Methodist church, a general store, a gin, and a lumberyard. Wade City did not prosper, however, and by 1914 its population had decreased to thirty-five. The post office ceased operation in 1922.

Around 1936 Wade's heirs petitioned for the site of Wade City to revert to them, arguing that the town never developed and showed no promise of doing so and that the land would be more valuable as ranchland. The petition was granted, and Wade City reverted to pastureland; Casa Blanca continued to be an independent community, but by 1945 only ruins remained.
