The architectural history of Chigi Palace spans more than three centuries during which several projects and continuous adaptations to the ever-changing needs of the Palace have followed. The Palace, overlooking the Piazza Colonna and the Via del Corso, was begun in 1562 by Giacomo della Porta. On 28 January 1578, the consistorial lawyer Pietro Aldobrandini, brother of the future Pope Clement VIII, purchased a house on Via del Corso. The architect Matteo Bartolini from Città di Castello was entrusted with the project. Aldobrandini already owned a property along the road that borders the so-called "Colonna island", connecting via del Corso with Montecitorio, he intended to unite the two properties. At the death of Pietro Aldobrandini, his son sold the properties to Paolo Fossano, who continued the work on the side of Via del Corso.
