Overview
The area of the Castelli occupies an ancient, fertile volcanic area which has allowed since ancient times a flourishing agriculture. The former crater is occupied by two lakes, the Lake of Nemi and that of Albano.
Starting from the Romans, it was an area frequented by the noblemen of Rome for its fresher climate during summer: the tradition was followed by the Popes which still have their summer residence in Castel Gandolfo, on the Lake Albano. Families which ruled in the castelli include Orsini, Colonna, Chigi, Aldobrandini and Ruspoli.
