The monastery of the Annunziata:

The origins of the Annunziata monastery are not clear to date: the Cammarata historian Domenico De Gregorio, referring in turn to Pirro as the first authoritative source, places its foundation in the era of the Abatellis, which in Cammarata can be placed between 1435 and 1500.

​ Some documents that speak specifically of the Monastery of the Annunziata di Cammarata are kept in the Archives of the Mother Church, studied by De Gregorio. They basically report information on the abbesses who succeeded one another over the centuries, on the dates of their election or death, as well as on that of the nuns. Unfortunately, the archives of the monasteries were lost during the suppressions, an element that leaves a great void for historical research. ​

On the side of the church you can see two high sheared walls and it could be plausible to think that they belonged to a body of the monastery perpendicular to it.  Certainly the building was not small, as it housed up to 30 nuns, and was equipped with well-defined environments such as the refectory, the kitchen, the novitiate, the infirmary and, most likely, a cloister.  (could this be the beam sometimes mentioned in the documents?).  For the cloistered nuns the cloister was a necessary place for religious life, where they took air, recreations often took place, strolled and often worked, protected from the sun, rain and bad weather. ​ The high door on the perimeter wall could also suggest a building  collapsed  two-story and it  could be  to be  it was a service exit. but these are just guesses at the moment
