During the 19th century the history of Puerto Vallarta, then called El Carrizal or Las Peñas, was linked to the history of the Sierra towns of San Sebastián del Oeste, Talpa de Allende and Mascota. While today these towns are considered quaint tourist destinations, during much of the 18th century, Mascota was Jalisco's second largest town, after Guadalajara. Mascota and its neighboring towns located in the high plateaus of the Sierra, developed as agricultural towns to support the growing mining operations in the Sierra.
