it easier for the citizen to require several facilities in the city. Some of the libraries also have a physical enclosure—among them the historic Octavio Paz Ibero-American Library of the University of Guadalajara and the Public Library of the State of Jalisco located in the adjoining city of Zapopan—with options for querying digital information over the Internet. The Jalisco Regional Museum (formerly the seminary of San José) was built at the beginning of the 18th century to be the Seminario Conciliar de San José. From 1861 to 1914, it housed a school called Liceo de Varones. In 1918, it became the Museum of Fine Arts. In 1976, it was completely remodeled for its present use. The museum displays its permanent collection in 16 halls, 15 of which are dedicated to Paleontology, Pre-History, and Archeology. One of the prized exhibits is a complete mammoth skeleton. The other two halls are dedicated to painting and history. The painting collection includes works by Juan Correa, Cristóbal de Villalpando and José de Ibarra.

The historical center hosts religious and civil colonial buildings, which are noted for their architectural and historical significance and are a rich mix of styles that are rooted in indigenous cultural contributions (mainly from Ute origin), incorporated in the Mozarabic and castizo, and later in modern European influences (mainly French and Italian) and American (specifically, from the United States). Guadalajara's historical center has an assortment of museums, theaters, galleries, libraries, auditoriums and concert halls, particular mention may be made to Hospicio Cabañas (which dates from the 18th century), the Teatro Degollado (considered the oldest opera house in Mexico), the Teatro Galerías and the Teatro Diana. The Hospicio Cabañas, which is home to some of the paintings (murals and easel) by José Clemente Orozco, was declared a World Heritage Site by UNESCO in 1997. Among the many structures of beauty is the International Headquarters Temple of La Luz del Mundo in Colonia Hermosa Provincia, which is the largest in Latin America.
