The Atenco Hacienda is not the largest hacienda in Mexico, but it is the oldest, according to a plaque on its main gate. It is the oldest livestock producer on the continent, a tradition still maintained, mostly producing bulls for bullfights. The hacienda was founded by a cousin of Hernán Cortés called Juan Gutiérrez Altamirano around 1528 with an area of about 30,000 hectares and 2,000 workers. It continued to operate until the Mexican Revolution when it was divided into sixteen parts. The main house and other buildings now only occupy about 3,000 square meters with five workers.
