It was built by the Franciscans and construction began in 1667. 

After several destructions of this temple due to floods, its construction was completed in 1784. 

Its carved pink quarry façade is a beautiful example of Churrigueresque style. 

The temple has a Latin cross shape and is located in front of Jardín Unión, also known as Plaza de San Diego, where the famous tianguis (market) was established during the colonial era. 

Inside, it has an important collection of 18th-century paintings and the image of Christ of Burgos, donated by the Count of Valenciana. The image of the Immaculate Conception, dating back to 1735, stands out. 

The baroque-style organ was built in the second half of the 18th century.
