Palazzo Colonna is one of the largest and oldest private palaces in Rome. Its construction began in the 14th century at the behest of the Colonna family, who has resided there permanently for eight centuries. The façade of the Gallery towards Piazza Colonna is characterized by strongly overhanging architectural styles typical of mannerist architecture of the first half of the 20th century. A careful study of the original architectural and lighting project, together with the technological developments introduced over the years, led to the decision to maintain the general image conceived. The renovation of the Gallery involves the refunctionalization of the historic lighting fixtures and the creation of a luminous curtain, followed by lighting modifications to the light sources for the internal lighting of the shops, which better harmonize with the more general lighting project.
The general image initially conceived is not changed. A re-lamping intervention re-functionalizes the historic lighting fixtures with new technologies. A luminous curtain is created and for a sense of general harmony, the light sources inside the shops that animate the gallery are modified
