The "Palazzo Pubblico", built on 1300, had undergone, during the past centuries, repeated work to restore and consolidate its structure. At the end of 1800 it was practically destroyed and re-build once again by architect Francesco Azzurri (1884). Adjustament to new operative and service needs have substantially led to the creation of vertical connections. For the new lighting of all public and governmental interiors was deliberately constructed a lighting fixture that draws inspiration from the form of a wrought iron "cylindrical cage" torch holder standing on the building roof. This fixture, called "Cylindrical Cestello" (then mass produced by iGuzzini) houses twelve very-low voltage halogen lamps, with a controlled light beam, that can be tilted both vertically and horizontally thanks to a cardan joint. Given the great flexibility and the possibility it offers this fixtures have been used for the general lighting as well as for specific lighting in all the public area: passage, work tops, walls having particular decorations. They accompany the visitor from the portico, through the entrance hall, to the enormous staircase and landing up to the room of the "Sala del Consiglio Grande e Generale" and to the "Sala del Consiglio dei 12" characterising, stressing and unifying the official route.
