With a panoramic view from the inside of the domestic chapel of an aisle with a dome and cupola, the place holds altarpieces and a profuse baroque decoration. A number of outstanding niches hold images and relics of saints and shields of the first six religious orders that catechized in New Spain. The high altar is dedicated to the Virgin of the Rosary.
The museum has been opened to the public ever since 1964 in Tepotzotlan, the State of Mexico. It lodges in a building that goes back to viceregal times and housed Jesuit schools of Saint Martin and Saint Francisco Javier. The museum stands on a territory over 60 000 m2. It has kept accessories the communities had used those days, constructed and decorated between 1604 and 1767. Likewise, it exhibits novo-Hispanic pieces of great artistic and historic value proceeding mostly from what was the Museum of Religious Art of the Cathedral of Mexico. The museum thus accomplishes a double objective: show the history of its important seat and illustrate the three centuries of viceregal Mexico. Among the museums collections are the most representative signatures of the paintings of these times, as well as numerous characters of New Spain. The polychrome quilt wood sculptures, ivory carvings from the Philippines, silver and gold work done mainly of golden silver, all stand out to their fine quality. Most objects are essentially religious such as, for example, the textile used by priests for religious means.
