Thanks to a great man who left us a great testimony of the history of Cammarata, we took the text from the book "Cammarata news on the territory and its history" by  Monsignor Domenico De Gregorio .

The cult of S. Sebastiano will have been introduced there towards the end of the century. XV and the beginning of the following, because the benefit of S. Sebastiano was founded there with an act dated 7-10-1532 in nr. Federico Blanco di Cammarata and perhaps since then the church began to be called with the name of the saint. The benefit was under the patronage of the University. In the church there was the ancient brotherhood of the Madonna dell'Itria (in 1598 Antonio, son of Luca Traina left her, in nr. Pietro Cimino, onza one) which had to die out towards the century. XVIII. In the visit of 1540 the church of S. Sebastiano is remembered with these words: "Ecclesia di Santo Sebastiano in company terra de jure patronatus of li jurati di company terra". He had an income of one onza annus. In an act dated 11/26/54 a house is mentioned "sita et posita in hac terra Camerate et in contrata Platee publice seu di lo floor of the fountain ipsius terre, secus locum et ecclesiam S. Sebastiani dicte terre" (31). In a period of plague, perhaps at the end of the 1500s or at the beginning of the 1900s, the church was also dedicated to S. Rocco for having him protector in the epidemics so frequent at that time. In a document cited by Biancorosso the church is described as follows: "The aforementioned church of the glorious martyr S. Sebastiano and S. Rocco, where the congregation of the Soul of Purga torio of the aforementioned land is also aggregated, and in the main square of the same , in front of the main door of said church, there is a floor with a water fountain in the middle with its degrees of carving, in the middle of which there is a column with a small bridge, above it a pedestal with a statue of giroglifico marble representing solerata in different bodies giroglifico marble representing Cammarata, on the right side there is a solerata house in different bodies above which the annual fees are made to said congregation that go down to the sum of onza 1 to grain 13, on the left side there is the loggia of the university of that land where the pawns that are currently destroyed are released and banished; the facade of said church is of stucco, the main door is of carving and masterful with a la pide on the door, where you can read the dedication and the year of rebuilding in better shape with the image of the glorious St. Sebastian, with the arms of Duke Francesco Branciforti "(32).

On the plaque we read these words: "Virgini Deiparae divi sque Sebastiano et Rocho aedem sacram vetustate pene collapsam renovata a fundamentis substructione Beneficiarius (33) in melio rem hanc faciem, sua et piorum civium pecunia restendam cu ravit. Year MDCXXXIII.

On the sides of the plaque are the words: Francisco duce et au spice = Under the auspices of Duke Francesco (Branciforti). The church was used for the assemblies of the civic council of the town which at the touch of its bell gathered in it to deliberate. Decisions and notices were promulgated from a small loggia to the left of the façade.

San Sebastiano was the seat of the civic council until the end of the feudal period; later, the decurions met either in the town hall or in another house. During the events of 1848 and 1860 the meetings were held in matrix.
