Don Bonifacio Garza traveled extensively in the late 1800s along the historic oxcart road from San Diego to Peña station, then to Rio Grande City, Roma, and Mier, trading and selling American and Mexican goods and carrying news to American Tejano ranches of Spanish and Mexican land grant ancestry. In 1893, he built this house, which also served as Hebbronville's post office for a few years. He distributed water and sold bloques de sillar, or limestone blocks, in mule-drawn carts, and his poetic greetings were legendary. Also known as Casa de Quatro Aguas, or House of Four Waterfalls, for its steeply pitched roof, the house was sold in 1898 to José Angel Garza, no relation, a Hebbronville pioneer and entrepreneur. It stands within the original townsite of Hebbronville, platted in 1894, and has been home to several descendants of Spanish pioneer families. The house also sheltered nuns exiled during the Mexican Revolution in the 1910s and nuns displaced during Mexico's Cristero War of the 1920s. It often housed professors of El Colegio Altamirano, a nearby Spanish-language school for grades one through six that operated from 1898 to 1958, and Profesora Emilia Davila was the last occupant. The two-story modified rectangular-plan dwelling features a rare Austrian-style gable-on-hip roof with dormers, and its thick limestone blocks with a caliche and stucco exterior helped regulate interior temperature year-round. Earlier thatch and wooden shingle roofs caught fire at least five times before a metal roof was installed. Today, the oldest house in Hebbronville remains a model of craftsmanship and a powerful connection entwined in Tejano history and Texas' Western past.
