The old San Agustín convent was one of the largest and most important in colonial times and dates back to the 16th century. 

In 1676, it was consumed by fire and was rebuilt, giving rise to a magnificent cloister and two temples that featured paintings by renowned artists such as Cabrera, Zurbarán, and Villalpando. 

With the Reform Laws, the convent was demolished, and the remains of the building were occupied by the University, which allocated them for the National Library. Recently, it has been restored again and will become a venue for exhibitions, conferences, concerts, theater plays, and other cultural activities.
