July 28 th 1754 they ignited the candles to contract the jobs related to the construction of the tower of the clock to place him among St. Oronzo square, said also the first square, and it places St. Francis, known as the second square. The mayor Geronimo Spennati and the chosen Archangelo Ayroldi and Anthoio Serio, together to the governor Diomede Pasca you and to the serviente of the court ducal Evangelist de Savior they brought him in one of the city, " and proper plazas in petra banni" where the serviente on command of the mayor began to banish the competitive bidding to tall voice: " Audite, who wants to apply to the fabrica of the building of the new clock to build him in the tower above the Door of the Bridge of said city, according to the sketch of the building sudetto, venghi to give the offer." After repeated invitations, he/she offered him to bring the work to good end the ledger mason Francesco Paolo it will Guzzle for 150 dukedoms. The specification of contract stipulated among the contracting parts is interesting for manifold reasons: in first place because it brings one detailed analysis of the things to do and of the materials to employ, and then because it describes the new construction in the least details and it shows in incontestable way that the ancient town administrators always foresaw the coverages of the stones with the plaster on which the protection was applied mortar of the same. The contract articulated on twelve points and the first one it foresaw the construction of a stairway of access to the tower and an arc of support to the new baluster behind the wall. The second prescribed to cover with once the arc set to the tower and to open a door "for mean the sudetta wall." The fourth article prescribed the construction of one "loggia in the publica places above to the sudetto new arc, with parapettata and frame to the part than above." The article you are it foresaw the erection of "two pillars from the floor of the first plaza to the plain foot of the second." This article shows that it places Sant'Oronzo and Plaza St. Francis, the first day-pupil to the boundaries and the inside second, they were on two different quotas and that to be joined it required the erection of the pillars on which to make to lean part of the new structure. The point seven performance " is kept to make a loggia to I return the tower, with parapettata and frame above and lower part cord, with four torches to I return." The master builder also " had to make that quantity of chiancatura that requires to I return the loggia and above the lamia of the clock." For the retrieval of the pieces, ledger it will Guzzle you/he/she could use of those drawn by the demolition of a situated construction behind the tower, or you/he/she could order of of it new to ledger zoccatori. The last point is then of fundamental importance because it involves the plastering of the new body of factory and the scialbatura: "him offeriscono it comparente and companions to do and cazzafittare the parapettata intiera of the fabrico toward the Plaza of S. Francis, as pure cazzafittare the said shop and the said cazzafittes have to be blank." The tower of the clock built from ledger it will Guzzle and from others ledger to Your service it was dejected in 1840 and you/he/she was reconstructed on project of of the architect Domenico Ciraci. In 1870, for the amplification of the actual Plaza of the Liberty, also the tower of architect Ciraci's clock was dejected and of it some rare images stay in only photo of epoch. The eighteenth-century tower, is found instead, drawn in a painting to temper not only placed perfectly in the sanctuary of country of Sant'Oronzo and show the architectural characteristics of the same tower of the clock but also of all the other buildings that had been built in the near. The specification of contract undersigned by the public administrators and from ledger it will Guzzle it furnishes an exhaustive key of reading around the constructions realized in the XVIII century above the building curtains and on the city towers and it reveals the fundamental characteristics of the same buildings that were not never unprovided of plaster and of mortar. His/her bridegrooms renovators of the boundaries have instead completely neglected this fundamental since the history has not only testified us through the documents of epoch but also through pictorial images raffrontabili with the zones not yet submitted to the jobs of consolidation and restauration. To subsequently fortify our reasonings around the strength state of the places before the interventions were effected on the façades of the buildings that look out upon on avenue Oronzo Quaranta to about ten, we are able produre a mountain of documents roused in numerous files public and private. But we believe both important to observe those same constructions and from the slope of avenue Oronzo Quaranta and from street Bixio Continelli and Stephen Trincherà up to offshore Madonna of the Stella, to become himself/herself/themselves account of the anomaly of those constructions completely skinned by a side and instead protected from the plaster and from the mortar from the other. We would also have been able to stretch a compassionate veil in order to the restauration of the boundaries, but considering that how much you/he/she is happened you/he/she has found the guarantee of the Superintendence to the Monuments in Bari and also of an artistic manager, we attend to be able to read and to comment the relationships produced in worth by the one and by the other.
