The parish church of the San Andrés municipality was begun in the first third of the 16th century and finished in the first half of the 17th. The main façade is made of gray sandstone with three levels on which is a very large image of the Apostle Andrew, crucified on an X. The first contains the main entrance into the building, which is a simple arch with spandrels decorated with flowers. Just outside the door, there is a holy water font which is probably from the 16th century. The doorway niches contain images of San Bernardino and San Antonio, which was not common during the colonial period. The interior has only one nave as it was constructed in the 16th century. On the left side, there is a chapel of the Virgin of Solitude, which was constructed in the middle of the 18th century. It contains a Churrigueresque altar, with highly decorated pilasters. The decoration on the cupolas were done in the second half of the 18th century and redone at the end of the 19th. This chapel also contains a large number of paintings which date back as far as the 17th century.
