Not much is known about the ornamentation of the Quinta Bella Oratory, there are few testimonies found and they all refer to pieces exquisitely manufactured and with rich materials, however all was ransacked and looted. It is known that all the imagery was brought from Europe and that the organ was acquired in France in 1873. As mentioned previously, there is only an image, rescued from a neighbor of the sector after there was a robbery in the oratory. It is the image of the Virgin Mary and is made in polychromatic wood.

We can also see what is left of the High Altar, which is framed by fluted columns of the Corinthian type that end at a higher altitude in a triangular pediment and that the niche is ornamented with moldings of cherubs.

The image of the Virgin has already been restored and the people in charge are only waiting for the adequate time to exhibit it, thus this small temple is also waiting to be rescued from its permanent oblivion.
