The story began in 1566. The Viceroy of New Spain, Don Luis de Velazco, granted land on the riverside of the Laja River to Captain Don Diego de Peguero, who named it Estancia San Antonio la Petaca. For more than 150 years, "La Petaca" served as a shelter for Spanish troops providing protection during the transportation of silver from the mines of Guanajuato. It was a mandatory stop for carriages en route to the north of the country along the "Camino Real de Tierra Adentro."

In 1750, the Hacienda was sold to Don Antonio de Lanzagorta Urtusuastegui, a Spaniard from Castile, who changed the name to Hacienda La Petaca.

An important historical event was carried out by Don Antonio's son, Juan José Francisco Lanzagorta de Inchauregui, and his friend Ignacio Allende, who met at La Hacienda la Petaca to plan the independence movement and are currently considered national heroes.

Another relevant historical event was on September 16, 1810. Around 3 p.m. that day, a handful of insurgents crossed the Laja River at the Hacienda la Petaca.

Some of its laborers were among the first to join the cause of the War of Independence. In the central courtyard of La Petaca, some original arches are preserved, which Don Antonio de Lanzagorta commissioned in memory of his homeland

La Petaca, with over 3,000 hectares in its time, became one of the most prosperous haciendas in the region. From cattle ranch to gold and silver storehouse. Surrounded by mesquite trees, its rooms connected by tunnels and escape routes, and its two chapels: one dedicated to the Virgin of Guadalupe, the other to the patron saint, Saint Anthony of Padua. Its legendary "Gallera," remnants of aqueducts, and hot springs will remain a symbol in the region's history.
