The catacombs of the Beaterio or also called as the low pantheon, was the place were the burials of an ancient order of beatified Franciscan tertiaries of the 17th century were made.

The Beaterio of Cádiz was founded in the 17th century, specifically in the year 1633, its foundation was made by María José Isabel under the 3rd order of San Francisco.

About this Beaterio there was not barely information collected, only the one which appears in the book of Adolfo de Castro called "Los nombres de las calles y plazas de Cádiz”, in which he says that Valverde street was called in the past Calle del Beaterio because on the same street there was a Beaterio.

After the departure of the Beatas, a company was set up in this building that taught women at risk of exclusion the art of sewing. Years later, the entire building was demolished except the low pantheon, which was the place of burial of the ancient Order of Beatas. In the middle of the 19th century, a new residential building was built in which the catacombs were conserved in order to give them a new use.

We know that the place was used until 1947, after the explosion suffered by Cadiz due to the detonation of a set of mines that were stored in the Hydrographic Institute, this caused a destruction and the fall of the top of the building.

In the Civil War, a group of neighbors of the building hid in the small hole located in the lowest level of the place
