The Hacienda de la Ferrería de Flores is about 8 km south of the city proper near the Cerro de la Ferrería mountain. The main house has been completely restored to what it was in the 19th century. It was an industrial hacienda dedicated to the production of iron. The site contains the most important archeological ruins in the state, with pyramidal structures and artifacts dating back over 2,000 years. It was built by a small agricultural society that lived off of corn, beans and squash, along with hunting and gathering.
