Rome (the "Comune di Roma") is part of the province Rome ("Provincia di Roma"), which in turn belongs to the region Latium ("Lazio"). The mayor of Rome is responsible for an area that is much larger than the city of Rome. The city and the area surrounding it are divided in 19 "Municipi", Municipalities (until 2001 they were called "Circoscrizioni", Circumscriptions). Each Municipality has a president and a certain autonomy. The area for which the Superintendency ("Soprintendenza") is responsible forms part of Municipality XIII (Ostia) and the city of Fiumicino ("Comune di Fiumicino"). Fiumicino is independent from Rome. In other words: two mayors and one president are responsible for the archaeological area: the mayors of Rome and Fiumicino, and the president of Municipality XIII.
The black interrupted line indicates the boundaries of the area for which the Superintendency is responsible.The Superintendency of Ostia is responsible for part of Fiumicino, and for the entire Municipality XIII, with the exception of the presidential estate of Castel Porziano and the park of Castel Fusano, that is an urban park under the jurisdiction of the Superintendency of Rome. The archaeological area has three subdivisions: the area of the excavations of Ostia Antica, the museum of Ostia, and the remaining area and museums. At present Marina Sapelli Ragni is the Superintendent for the full area. Angelo Pellegrino is Director and Coordinator only for the excavations of Ostia Antica and the museum. Certain areas may be entrusted to inspectors. Flora Panariti for example is responsible for the Infernetto area. The Superintendency of Rome is responsible for all other Municipalities. The remainder of Latium has its own Superintendency. The Ministry of Cultural Heritage and Activities ("Ministero per i Beni e le Attività Culturali") is responsible for all Superintendencies.
Municipality XIII (Ostia).The legal power of each Superintendency is very great. They can for example stop building activity by putting archaeological constraints over an area, limit the depth of digging, forbid an area, suggest a specific type of building, and limit the height of a building. All archaeological excavations are under the jurisdiction of a Superintendency. A Superintendency can employ universities or external consultants for a specific excavation, including private companies with experience in the archaeological field.
